Hotel Room Block Management Glossary

Definitions of key terms used in hotel room block management — room nights, attrition, pickup, cutoff dates, rooming lists, and more.

A

Assigned

What does "assigned" mean in hotel room block management?

Rooms that a coordinator has committed to groups or departments, but the hotel has not yet confirmed. Assigned rooms are counted toward demand but not yet toward pickup. This is one of the four per-night metrics tracked for every room block, alongside blocked, picked up, and pending.

Attrition

What is attrition in a hotel contract?

A contractual penalty for not using committed room nights in a hotel room block. If a contract specifies 80% attrition, the organization must pick up at least 80% of blocked rooms per night or pay a penalty on the shortfall — typically the full room rate for each unused room night. Attrition is usually calculated per night, not in aggregate, making it the single most important financial risk in room block management.

Blackout Dates

What are blackout dates in a hotel room block contract?

Dates on which a hotel will not honor the negotiated group rate or accept new reservations into the block, usually because demand is expected to be high enough to sell those rooms at a premium. Blackout dates are written into the contract and often fall around holidays, citywide conventions, or peak local events that overlap your program. For a coordinator, they matter most at the edges of a stay: a guest who wants to arrive a day early or leave a day late may find that night blacked out and priced at the hotel's public rate instead of the group rate. Confirm blackout dates before promising attendees flexible arrival and departure, and check whether they fall on your shoulder nights.

Blocked

What does "blocked" mean in hotel room blocks?

The number of rooms contractually reserved for a given night in a hotel room block. This is the committed inventory — the baseline against which pickup and attrition are measured. When a hotel says you have "100 rooms blocked," they mean 100 rooms per night for the dates in your contract.

Cancellation Clause

What is a cancellation clause in a hotel contract?

The section of a hotel contract that defines what the group owes if it cancels the entire event, and by when. Cancellation penalties usually escalate on a sliding scale tied to how close to arrival the cancellation happens — for example, 50% of anticipated room revenue if you cancel 90 days out, rising toward 100% inside 30 days. Unlike attrition, which penalizes unused rooms within a program that still happens, cancellation applies when the whole block goes away. Read this clause alongside the cutoff date and any force majeure language, because together they determine your total exposure if plans change. Negotiating a graduated schedule, and credit for rooms the hotel resells, is one of the highest-value moves in any room block contract.

Citywide

What is a citywide event in hotel room block management?

An event large enough that a single hotel cannot house all attendees, so rooms are blocked across many hotels in a market, often coordinated with the local convention and visitors bureau or a housing bureau. Citywide conventions drive peak demand across an entire city, which is why they frequently show up as blackout dates in unrelated groups' contracts. For the organizer running one, the challenge is tracking pickup, cutoff dates, and attrition across dozens of separate contracts at once — each hotel with its own terms — rather than a single block. Per-night visibility across every property becomes essential, because attrition is calculated hotel by hotel: a shortfall at one property is not offset by strong pickup at another.

Commissionable Rate

What is a commissionable rate in hotel contracts?

A hotel room rate that includes a travel agent commission, typically 10%. If the commissionable rate is $200 and the commission is 10%, the net cost to the booking organization is $180. Group contracts may quote either commissionable or net rates — understanding which type is being quoted is critical for accurate budgeting.

Comp Ratio

What is a comp ratio in a hotel contract?

The formula that determines how many complimentary rooms a group earns from paid room night pickup, most commonly expressed as "1 per 40" — one free room night for every 40 picked up — or "1 per 50." The comp ratio is a standard contract concession and is usually calculated on cumulative room nights across the whole block, not per night. A more favorable ratio, such as 1 per 35 instead of 1 per 45, meaningfully lowers your effective cost, which makes it a common negotiation lever. Because comps are earned on actual pickup, a weak block yields fewer of them. Always confirm whether the ratio counts all room nights or only revenue-generating ones, and reconcile the comps you earned against the final pickup report.

Comp Room

What is a comp room in a hotel contract?

A complimentary hotel room earned based on room night pickup volume, typically expressed as a ratio like "1 per 40" — one free room for every 40 room nights picked up. Comp rooms are a standard contract concession and are usually calculated on cumulative room nights picked up across the entire block, not per night. They represent significant value and should always be tracked and claimed.

Concessions

What are concessions in hotel contracts?

Negotiated extras beyond the base room rate in a hotel contract. Common concessions include complimentary or discounted parking, Wi-Fi, meeting space, food and beverage credits, suite upgrades, and early check-in or late checkout privileges. Concessions vary significantly between properties and markets, making historical tracking valuable for future negotiations.

Cutoff Date

What is a cutoff date for hotel room blocks?

The deadline for submitting the final rooming list — guest names assigned to specific rooms — to the hotel. After this date, unbooked rooms are released back to the hotel's general inventory and may no longer be available at the contracted rate. Cutoff dates are typically 21-30 days before the event and are one of the most critical deadlines in room block management. Also called the "cut date."

F&B Minimum (Food & Beverage Minimum)

What is an F&B minimum in a hotel contract?

A contractual commitment to spend a set dollar amount on food and beverage at the hotel, separate from room revenue, in exchange for the group rate or meeting space. If the group's catering, banquets, and receptions fall short of the minimum, the hotel charges the difference as a shortfall, often plus tax and service charge. F&B minimums appear most in contracts that bundle guest rooms with event space, and they can rival attrition as a source of unexpected cost. Track the F&B commitment alongside your room block terms so the full obligation is visible in one place. When negotiating, confirm what actually counts toward the minimum — some hotels exclude tax and service charge from credited spend — and whether an unmet minimum can be reallocated to other services.

Force Majeure

What is a force majeure clause in a hotel contract?

A contract clause that excuses one or both parties from their obligations when circumstances beyond their control — natural disasters, government action, or other events that make performance illegal or impossible — prevent the event from happening. A strong force majeure clause can release a group from attrition and cancellation penalties when, say, a hurricane closes the destination or a public-health order bans gatherings. The exact wording matters enormously: a narrow clause covering only "acts of God" protects far less than one that also addresses impracticability and materially reduced attendance. Read force majeure together with the cancellation clause, since they govern different exits from the same contract. It is among the terms most worth reviewing carefully before signing, because it decides who bears the loss when an event cannot proceed.

Group Rate

What is a group rate for hotel room blocks?

The negotiated per-night room rate a hotel offers for a block of rooms held for a single event, typically lower than the hotel's public retail rate in exchange for volume and a commitment to fill the rooms. The group rate is the headline number in a room block contract, but it is rarely the whole cost: resort fees, taxes, and parking can add substantially, and whether the rate is net or commissionable changes what the group actually pays. Group rates are usually guaranteed only for the contracted dates and can exclude blackout dates. Comparing group rates across competing hotels means normalizing for those add-ons and for concessions, not just reading the nightly figure — a rate that looks higher can be cheaper once waived fees are counted.

Guarantee / Deposit

What is a guarantee or deposit in a hotel room block contract?

The money a hotel requires up front, or a credit guarantee it holds, to secure a room block before guests arrive. A deposit schedule spreads payments across milestones — a percentage at signing, more at cutoff, the balance before arrival — and those funds are typically credited against the master account or forfeited under the cancellation clause. Individual reservations may also carry a guarantee, such as a first-night room-and-tax charge that protects the hotel against no-shows. For a coordinator, the deposit schedule is a cash-flow deadline as much as a contractual one: missing a deposit date can jeopardize the rate or the block itself. Track deposit due dates alongside the cutoff and attrition deadlines so none of them slip through.

Hotel Brief

What is a hotel brief in event planning?

An AI-generated intelligence summary for a hotel property, aggregating an organization's rate history, public retail rates for comparison, contract term patterns (attrition, cancellation, comp room ratios), and known contacts at the property. Hotel briefs help negotiators understand their position and identify leverage points before entering rate discussions.

Housing Bureau

What is a housing bureau in event planning?

A third-party service, often affiliated with a convention and visitors bureau, that manages hotel reservations across multiple properties for large citywide events. Attendees book through the housing bureau's central system, which distributes them into the various contracted blocks and reports pickup back to the organizer. Housing bureaus exist because no single hotel can absorb a citywide, and coordinating dozens of blocks by hand is impractical. The trade-off is a layer between the organizer and each hotel: reservation data, cutoff enforcement, and rooming details flow through the bureau rather than directly. Organizers still own the underlying contracts and remain responsible for attrition at each property, so keeping an independent, per-night view of pickup across all hotels matters even when a bureau runs the booking.

Incidentals

What are incidentals in hotel group billing?

The charges a guest can run up beyond room and tax during a stay: meals, parking, spa, minibar, movies, phone, and similar extras. At check-in a hotel usually authorizes a hold on a credit card to cover anticipated incidentals. The key question in group billing is routing — whether incidentals post to the individual guest's own card or roll up to the group's master account. Contracts and rooming lists specify this per guest, and "room and tax to master, incidentals to guest" is the most common arrangement, keeping the group from absorbing personal charges. Getting incidental routing right on the rooming list is what prevents billing disputes at checkout and keeps the post-event master account clean and reconcilable.

Intake Form

What is an intake form for hotel rooming lists?

A shareable link that lets external group coordinators, department heads, or other contacts submit guest names and room requests without needing an account in the room block management system. Intake forms are scoped to a specific event, can be set to expire, and feed directly into the rooming list workflow. They eliminate the back-and-forth email chains typically required to collect guest names.

Last Room Availability

What is last room availability in a hotel contract?

A contract provision under which the hotel agrees to sell rooms at the group rate right up to its last available room of that type, rather than capping the block at a fixed number. With last room availability (LRA), late-booking attendees keep getting the group rate even after the original block fills, as long as the hotel has inventory. Without it — a non-LRA agreement — once the blocked rooms are gone, additional guests pay the higher public rate or book elsewhere. LRA is a valuable concession for events with uncertain final headcount, because it shields attendees from rate creep while the group still controls its committed inventory and attrition exposure. Confirm whether your rate carries LRA before assuming late bookings will match the group rate.

Master Account

What is a master account in hotel group billing?

The central hotel bill for a group, where the charges the organizer agrees to cover are consolidated instead of billed to individual guests. What posts to the master account is defined in the contract and on the rooming list: a common setup routes room and tax to the master while incidentals go to each guest's own card, or routes everything for VIP rooms to the master. The master account is where deposits are credited, where attrition and F&B shortfalls are charged, and what post-event reconciliation ultimately audits. Getting billing instructions right per guest is what keeps it accurate. A clean master account at checkout, matched line by line against the contract and the rooming list, is the goal of the entire billing workflow.

Negotiation Playbook

What is a negotiation playbook for hotel contracts?

An organization's own set of rules for negotiating hotel contracts — the terms it cares about, preferred language for each, ranked fallback positions, and a walk-away point where a term becomes a deal-breaker. A playbook can be seeded from an existing contract (using a strong one as precedent to aim for, or a tough one as a cautionary example to guard against) or built by answering a few questions about the event. Contracts are then reviewed against the playbook so the same standards apply to every property, every time — turning institutional negotiating knowledge into a reusable asset. A playbook is decision support for the negotiation, not legal advice.

Net Rate

What is a net rate in hotel contracts?

The actual room rate paid by the booking organization — no commission included. Most group hotel contracts quote net rates. Compare with commissionable rate, which includes a travel agent commission (typically 10%). Knowing whether a quoted rate is net or commissionable is essential for accurate budget comparison across properties.

No-show

What is a no-show in hotel room block management?

A guest who holds a confirmed reservation in the room block but never checks in and never cancels. No-shows matter because most group reservations carry a first-night guarantee: when a guest fails to arrive, the hotel charges one night's room and tax, and whether that lands on the guest's card or the group's master account depends on how the reservation was set up. No-shows also distort pickup — depending on the contract, a no-show room may still count as picked up for attrition or may be released. For a coordinator, no-shows are a reconciliation item: comparing the rooming list against actual arrivals surfaces who did not show, so the resulting charges can be verified rather than paid blind.

Peak Night

What is a peak night in hotel booking?

The highest-demand dates during an event — usually the middle nights when all attendees are present. Peak nights fill up first, may command higher rates than shoulder nights, and are least likely to trigger attrition penalties because demand naturally exceeds supply. Rate negotiations often focus on peak night pricing since these dates represent the largest share of total room night spend.

Pending

What does "pending" mean in room block management?

Rooms that have been assigned to guests but are awaiting hotel confirmation. Pending rooms represent the gap between what the coordinator has committed and what the hotel has officially acknowledged. One of the four per-night metrics tracked for every room block, alongside blocked, assigned, and picked up.

Per Diem Rate

What is a per diem rate in hotel booking?

A fixed maximum lodging rate that a government or organization allows its travelers to spend, most familiar as the U.S. federal per diem used by government and many corporate and university travelers. When an event draws attendees bound by per diem, the group rate has to be negotiated at or below that ceiling for the relevant nights, or those attendees cannot book in the block. Per diem rates vary by city and by season, which can make a compliant group rate hard to secure in expensive markets or on peak dates. For coordinators serving government, military, or per-diem-bound corporate groups, confirming the rate falls within the applicable per diem is a gating requirement, not a nice-to-have — miss it and pickup collapses as attendees book compliant rooms elsewhere.

Pickup

What is pickup in hotel room blocks?

The number of room nights the hotel has confirmed as booked by named guests. Pickup is the metric that determines whether an organization meets its contractual attrition commitment. The gap between blocked rooms and picked-up rooms is attrition exposure — the unused room nights that may incur penalties. Pickup is tracked per night because hotels typically calculate attrition on a per-night basis.

Pickup Report

What is a pickup report in hotel room block management?

A hotel-generated summary showing how many rooms in a block have actually been booked by named guests, typically broken out by night and by room type. Coordinators request pickup reports throughout the booking window to see reservations against the contracted block and judge whether the group is on track to meet its attrition commitment or heading for a shortfall. The gap between blocked and picked-up rooms is the attrition exposure the report makes visible. Because hotel-provided reports can lag or aggregate away the per-night detail that attrition is actually calculated on, keeping an independent, date-level pickup view — and reconciling it against the hotel's numbers — is how coordinators catch problems while there is still time to add demand or renegotiate.

Rate Protection Clause

What is a rate protection clause in a hotel contract?

A hotel contract provision that keeps the group's contracted rate from being undercut by the hotel's own public pricing — often written as a "best available rate" guarantee, promising the group rate stays at or below the lowest rate the hotel offers the public for the same dates. When a rate check finds the hotel selling rooms below the contracted rate, a rate-protection clause is the leverage to push back: its exact wording can be quoted to the hotel in a rebuttal. Not every contract includes one, which is why it is worth confirming during negotiation and noting plainly when it is absent.

Rebate

What is a rebate in a hotel room block contract?

A per-room-night amount the hotel agrees to pay back to the group or organizer — effectively a share of room revenue returned to help fund the event. A rebate of $10 per room night on a block that picks up 2,000 room nights returns $20,000, which organizers often apply to offset planning costs, staff rooms, or attendee subsidies. Rebates are negotiated concessions and are usually credited against the master account or paid out after the event once final pickup is known. They differ from commissions, which go to a travel agent or third-party planner rather than back to the group. Because a rebate scales with pickup, model it against realistic pickup rather than the full block when weighing it against a lower nightly rate.

Resort Fee

What is a resort fee in a hotel contract?

A mandatory daily charge some hotels add on top of the room rate, ostensibly bundling amenities such as Wi-Fi, pool access, the fitness center, or local calls. Resort fees matter in group contracts because they can add $25 to $50 per room per night on top of the negotiated group rate, materially changing the true cost of a block even when the headline rate looks competitive. Waiving or reducing the resort fee is a common, high-value concession — across a large block over several nights, a waived fee can save more than a modest rate cut. Always confirm whether a quoted rate includes or excludes resort fees before comparing hotels, and get any waiver written into the contract rather than promised verbally.

RFP

What is an RFP in hotel sourcing?

A Request for Proposal — the document an event organizer sends to hotels to solicit bids for a room block and any meeting space, specifying dates, room night patterns, meeting requirements, and desired concessions so properties can respond with rates and terms. The RFP is the opening move in hotel sourcing: responses are compared side by side to shortlist properties before negotiation and contracting. A well-built RFP states the group's pattern night by night and names the concessions that matter, so proposals come back in comparable, apples-to-apples form. Blocks approaches this as sourcing intelligence — finding hotels in a market, tracking quotes side by side, and negotiating from your own rate history. The clearer and more specific the RFP, the more usable the proposals that come back.

Rolling Attrition

What is rolling attrition in a hotel contract?

An attrition structure where the group's allowed shortfall is measured and tightened in stages as the event approaches, rather than assessed once at a single cutoff. A rolling schedule might let the group release 20% of the block at 90 days out with no penalty, another 10% at 60 days, and lock the remainder at 30 days — so the room nights you can shed without cost shrink over time. Rolling attrition rewards early, honest forecasting: releasing rooms you know you will not fill at an early checkpoint avoids penalty on them later. For a coordinator it turns attrition from one high-stakes deadline into a series of decision points, each needing a current, per-night pickup view to decide how much of the block to hold or return.

Room Block

What is a hotel room block?

A set of hotel rooms reserved at a negotiated group rate for an event. Each room block belongs to one hotel and one event, with defined check-in and check-out dates, a nightly rate, and a specified number of rooms per night. Organizations can have multiple room blocks per hotel (for different room types or rate tiers) and multiple hotels per event. The room block is the fundamental container for inventory tracking.

Room Night

What is a room night in hotel management?

The fundamental unit of measurement in hotel room block management. One room occupied for one night equals one room night. A guest staying 4 nights in 1 room uses 4 room nights; 10 rooms for 5 nights equals 50 room nights. Contracts, budgets, and attrition penalties are all calculated in room nights, not room count. Per-night tracking is essential because rates, demand, and attrition risk vary by date.

Room Request

What is a room request in event planning?

A submission from a group, department, or individual who needs rooms for an event. Room requests represent demand — the rooms people need — before those rooms are assigned to specific hotel room blocks. A request typically includes the group name, number of rooms needed, check-in and check-out dates, guest names (if known), and any special requirements like accessibility or bed type preferences.

Rooming List

What is a rooming list in hotel management?

The final list of guest names assigned to hotel rooms, submitted to the hotel before the cutoff date. A rooming list includes each guest's name, check-in and check-out dates, room type, and any special requests. Hotels require rooming lists to confirm individual reservations within a room block. The rooming list is the deliverable that the entire room block management workflow builds toward.

Rooming List Audit

What is a rooming list audit?

The process of checking a hotel's returned copy of a rooming list against the organization's own records to catch discrepancies before they become billing errors. Each row is matched to a reservation by confirmation number first — so one booking is never mistaken for two different guests — and every difference is grouped into a category: a name mismatch, a date or room-type mismatch, a guest missing from the hotel's list, or an extra on the hotel's list. Accepted corrections become a changes-only email back to the hotel that lists only what needs fixing, each with its confirmation number. Nothing changes on the reservations until each correction is accepted.

Run of House

What is run of house in a hotel contract?

A rate and assignment arrangement in which the hotel commits to a single group rate for any standard room in the property, assigning specific rooms at check-in rather than guaranteeing a particular room type. Run of house (ROH) gives the hotel flexibility over its inventory and usually comes with a lower, simpler rate, since the group is not paying to lock in views, floors, or bed configurations. The trade-off is less control: under pure ROH a coordinator cannot promise a given guest a king bed or a high floor. For blocks where attendees just need a clean, consistent room at a predictable price, ROH simplifies both the contract and the rooming list; for VIP-heavy programs, negotiating a few upgraded room types alongside the ROH base is common.

Shoulder Night

What are shoulder nights in hotel booking?

Lower-demand dates flanking the peak event dates — typically the first and last nights of a room block when guests are arriving or departing. Shoulder nights often have lower pickup rates, may be priced lower than peak nights, and carry the highest risk of attrition penalties because fewer guests need rooms on those dates. Negotiating reduced commitment or flexible attrition on shoulder nights is a common and effective contract strategy.

Single / Double Occupancy

What is single versus double occupancy in hotel room blocks?

How many guests share a room, and often how that room is priced and set with beds. Single occupancy means one guest; double occupancy means two, whether in one bed or two. Some contracts quote the same rate regardless of occupancy, while others charge a per-person supplement above double, so occupancy affects both the budget and the rooming list. On the rooming list, occupancy drives bed configuration — a double-occupancy room may need two beds — and any shared-cost split between roommates. For coordinators, capturing occupancy accurately per room prevents check-in surprises, such as a couple assigned two twin beds or two colleagues assigned one king, and keeps room night math and billing aligned with what guests actually booked.

Stay to Play

What is stay to play in sports event housing?

A policy common in youth and amateur sports events that requires teams to book their lodging through the event's official room block in order to be eligible to compete. Stay to play guarantees the organizer the room night volume promised to host hotels, which in turn funds the event and secures favorable rates and facility access. For the housing coordinator it concentrates demand into managed blocks and sub-blocks — typically one per team or club — that must be tracked, named, and reconciled before cutoff. The model draws scrutiny when families feel forced into specific hotels, so clear communication, fair rates, and accurate per-team pickup tracking matter. Enforcement usually ties a team's tournament registration to a confirmed booking in the sanctioned block.

Sub-block

What is a sub-block in hotel room block management?

A subdivision of a larger room block allocated to a specific group, team, department, or attendee category — tracked separately while still rolling up to the master block. Sub-blocks let a coordinator hand each department lead or team manager responsibility for their own rooms — their own allocation, their own names, their own pickup — without losing the consolidated view of the whole event. In sports and citywide events especially, a single hotel block may hold dozens of sub-blocks, one per team or club. Managing them well means per-sub-block pickup and cutoff tracking, so a shortfall in one group is visible against the overall attrition commitment. Sub-blocks are how large, multi-group programs stay organized without fragmenting into separate contracts.

TBD Room

What is a TBD room in hotel room blocks?

A room that is allocated within a room block (counted against committed inventory) but does not yet have a guest name assigned. TBD rooms are still guaranteed — the hotel holds the room even without a name attached. Guest names must be provided before the cutoff date. TBD rooms are common early in the planning process when organizations know they need the rooms but have not yet collected names from all departments or groups.

Walk Clause

What is a walk clause in a hotel contract?

The contract language governing what the hotel owes when it "walks" a confirmed guest — turns them away because the hotel is oversold — and sends them to another property. A protective walk clause requires the hotel to pay for comparable accommodations nearby, transportation to and from, and often a phone call home and a return to the group's hotel the next night at no charge. Walk clauses matter most on peak nights, when overbooking is likeliest and your attendees are most numerous. For a coordinator the risk is reputational as much as financial: a VIP walked on arrival reflects on the organizer, not the hotel. Negotiating clear walk protections, and flagging VIPs to the hotel in advance, is how you reduce that exposure.

Wash (Wash Factor)

What is a wash factor in hotel room block management?

The practice of proactively cutting a room block down to realistic expected pickup — "washing" out rooms the group knows it will not fill before they trigger attrition penalties. If history shows an event picks up about 70% of its initial block, applying a wash factor means reducing the block toward that level at an early release point instead of carrying, and later paying attrition on, rooms that were never going to sell. The wash is a forecasting discipline: it trades a larger held block for a smaller, more accurate commitment. Coordinators apply it using prior-year pickup and current booking pace, ideally per night, since shoulder nights wash more than peak. Done well, washing a block turns attrition risk into a managed number rather than a year-end surprise.
