Peak Night

How do you calculate the percentage of peak night on a room block?

Two different sums go by that name, and they answer different questions. The first is concentration: how much of the block sits on its busiest night. The second is performance: how much of that busiest night you actually filled. Work out which one you are being asked for before you quote a number.

• Concentration — peak-night rooms divided by the block’s total room nights. On the block below, Friday’s 30 rooms against 85 total room nights is 35%; the two peak nights together are 60 of 85, or 71%.
• Performance — rooms picked up on the peak night divided by rooms contracted on that night. Friday’s 28 picked up against 30 blocked is 93%.

Which percentage of peak does a contract mean?

Almost always the second one, and as a floor you have to reach rather than a result you report. “The Group will pick up no less than 80% of the contracted peak night” sets a 24-room commitment on a 30-room peak night, and everything below that line is attrition. If a clause names a percentage of peak, find out whether the percentage is applied to the peak night alone or to every night in the pattern — those are different contracts with the same sentence in them.

Hotels also use the peak-night room count to size the deal in the first place. When a sales manager describes your group, the number they quote is the peak night: it is what constrains the property, and it is the figure that decides whether your business fits at all.

Friday and Saturday carry 60 of this block’s 85 room nights, so that is where the rate negotiation is really happening — and where a slip costs the most. Read peak-night pickup on its own as well as inside the 86% block average.

What does “cumulative peak nights” mean?

Inside a contract, cumulative is the opposite of per night: it is the measurement basis. A cumulative clause adds your room nights across the whole pattern and compares one total against one commitment, so a strong peak night covers a weak shoulder. A per-night clause judges each date on its own, and the shortfalls do not net out against the surpluses. On the block above, an 80% floor measured per night owes $378 for one soft Sunday and, measured cumulatively, owes nothing.

Outside a contract, “cumulative peak nights” usually means a running total kept by a hotel or a convention bureau: the peak-night rooms of every group booked on the same dates, added together, to show how much of the house or the city is already committed. That is a capacity figure about them, not a commitment figure about you. When a sales manager quotes it, they are telling you how tight the date is.

What does “3,000 peak nights” mean at a hotel?

It sizes an event by its single busiest night. An event described as 3,000 peak nights occupies roughly 3,000 rooms on the one night when the most attendees are in town, counted across every hotel holding rooms for it. It is not 3,000 room nights in total, and it is not 3,000 attendees.

This is citywide vocabulary, used by convention bureaus and hotel sales teams because the peak night is what actually constrains a market: a city absorbs a long event more easily than a short one with the same total room nights. Total room nights are a multiple of the figure — a 3,000-peak event on a four-night pattern with soft shoulders might run nine or ten thousand room nights. Applied to a hotel rather than an event, it is the same idea from the other side: how many rooms the property expects to have committed to groups on its busiest night.

How do you figure peak nights from a rooming list?

Count the rooms occupied on each date and take the highest. A rooming list gives you an arrival and a departure per room, which is a range rather than a count, so you have to expand it. A room arriving 4 March and departing 8 March occupies the nights of the 4th, 5th, 6th and 7th. It does not occupy the night of the 8th — that is the morning it checks out.

That one-night offset is where most hand-counted peak numbers go wrong. Tally each room against every night it actually occupies, then read the column totals.

Can an event have more than one peak night?

Yes, and most do. The peak above is five rooms and it falls on two nights, 5 and 6 March — sixteen room nights in total, with the 4th a shoulder holding two. Nothing in the definition says the peak is a single date.

Nor is it reliably in the middle. An event where everyone leaves on the last afternoon peaks earlier than one with a closing party, and a programme with a training day in front of it peaks later than the headline dates suggest. Which is the practical argument for tracking every night rather than a peak and an average: Blocks holds blocked, assigned, picked-up and pending per night for every block, so the shape of the stay is visible rather than inferred.
