A Passkey alternative built around your contracts
Passkey books rooms well inside the Cvent ecosystem. Blocks starts a step earlier — with the contract you signed — and stays through the cutoff, the attrition math, and the rooming list the hotel sends back. Easier to buy, faster to live on, and built around your contracts and deadlines — not just the booking site.
Blocks is a Cvent Passkey alternative built around your hotel contracts and deadlines. It reads the contract you signed, tracks attrition per night, alerts you before every cutoff, and audits the rooming list a hotel returns — by confirmation number. Attendees book and pay for their own rooms on a branded page too, so switching does not mean giving up the booking site.

“The booking site looks great, but nobody is watching the attrition clause I actually signed.”
Blocks reads the contract in under 60 seconds, pulls out the rates, cutoffs, and attrition terms, and tracks your exposure per night — so the deadline that costs money is on the block itself, not buried in a PDF.
“Pickup looks fine in the portal — until the hotel sends back a rooming list that does not match ours.”
Blocks audits the hotel’s returned list against your reservations by confirmation number, groups every discrepancy, and proposes corrections you confirm one by one. Nothing changes until you say so.
“Getting a quote and standing the platform up took longer than the lead time on the event.”
Blocks publishes its list pricing and imports the spreadsheet you already keep, so you are live in a day — no enterprise rollout, no quote cycle before you can see your own blocks.
What is the best Cvent Passkey alternative for contract-first teams?
If your risk lives in the contract — the attrition band, the cutoff date, the concessions you negotiated — Blocks is the alternative built for that. Blocks reads a hotel contract and extracts the rates, cutoffs, and attrition terms in under 60 seconds, then reviews the contract against your negotiation playbook and hands you a ranked issues list. That review is decision support, not legal advice. From there, every extracted deadline lands on the block and can sync to your calendar, and attrition is tracked per night against what you committed. Passkey is genuinely good at the booking layer — branded self-booking sites and real-time pickup reporting inside the Cvent stack — but its materials position it around managing reservations, not around reading your contract or working a buyer-side playbook. Blocks starts with the document that decides whether you owe money, and keeps working through the final rooming list.
How is Blocks different from Cvent Passkey?
Both tools run branded attendee self-booking, track pickup, and send milestone alerts, so the difference is where the center of gravity sits. Passkey is built around the booking layer of the Cvent suite: native integration with Cvent registration and marketing, real-time availability, and a shared portal the hotel and planner both open. Blocks is built around the buyer’s side of the deal — the contract, the per-night room-night math, the cutoff and attrition deadlines, the rooming list the hotel returns, and the hotel conversations themselves. Blocks models each hotel thread as a loop: what you sent, what you are waiting on, and what came back, with a thread flagged overdue when a hotel goes quiet for about three business days. It audits returned rooming lists by confirmation number and proposes corrections you confirm. Attendees book on a branded page in either tool; what differs is what the booking carries and where it lands. In Blocks, guests book and pay for their own rooms — an integrated booking-and-payment engine drawing from your real block inventory — and every booking lands against the contract, the per-night commitment that decides whether you owe money. In Passkey the reservation lands in the Cvent stack.
Do I have to leave Cvent to use Blocks?
No. Blocks is not trying to replace your event stack — it is the room-block system your stack does not give you. If your organization already runs registration, marketing, or attendee booking in Cvent, keep it. Blocks sits alongside as your system of record for contracts, deadlines, per-night pickup, and rooming-list accuracy. It imports the spreadsheets you already keep, exports to CSV or Excel whenever finance or a hotel needs a copy, and you can copy Blocks on your hotel email threads so the conversation history lands where the block lives. You do not have to rip anything out or wait on an enterprise migration. Many teams keep attendee booking in Cvent and run the contract, the attrition exposure, and the returned rooming list in Blocks. And if you would rather consolidate, Blocks runs branded attendee booking and payment too — guests book and pay for their own rooms on the same block — so staying in Cvent is a choice, not a requirement.
When Cvent Passkey is the right choice
Cvent Passkey is the right choice when the Cvent stack is the point. If you run large citywides already standardized on Cvent registration and marketing, and rely on established housing-bureau workflows where the hotel and planner share one live reservation portal, Passkey is built for exactly that and integrates natively with the rest of the suite — one login, one vendor, one dataset. Its real-time pickup and milestone alerts are genuinely strong, and reviewers praise on-demand, 24/7 access to reservation and rooming-list data. Blocks is the better fit when your leverage lives in the contract and your work is buyer-side — reading terms, tracking attrition per night, catching cutoffs, and auditing the list a hotel returns — with branded attendee self-booking on the same block, so the bookings and the contract math live in one place. Many teams still run both, with Passkey on the booking side and Blocks holding the contract, deadlines, and rooming list.
