Room nights and the block

Turn travelers into rooms per night, shoulder nights, total room nights, a block to contract and the attrition floor you'll owe below. Same math as the room-block guide.

Who needs a bed

Leave out locals who go home at night.

Two per room.

The nights
The contract

Cancellations, locals, people who book elsewhere.

Pickup you must hit before penalties.

Rules of thumb, not legal advice. Attrition and cutoff terms vary by hotel; read your contract and ask how they count pickup.

Exposure assumes the hotel charges the group rate for each room night under the floor. Some contracts charge less (lost profit only); some charge more.
