What is a hotel group booking?
A group booking is the hotel side of moving a lot of people at once. This cheat sheet covers how to think about one, a booking timeline and what to settle before you sign. The detail is further down.
How to think about it
- Two ways to set it up. Hold a room block at a negotiated rate, or suggest hotels and let guests book their own rooms.
- It's a contract. A contracted group booking guarantees the hotel a set number of rooms for agreed dates, and the attrition, cancellation and liability terms come with it.
- Demand sets the offer. Dates, season, demand, hotel type, how many rooms and which types, days of the week, location and amenities all shape the group rate a hotel offers.
- Ask for more than the rate. Parking, breakfast, early check-in, comp rooms and a longer name-change window can be worth more than a small rate cut.
A group booking timeline
- 90 days outScope the block, gather three to five proposals and shortlist two.
- 60 days outNegotiate the final rate and terms, sign the agreement, tell travelers how to book and pick a billing method.
- 30 days outUpdate the pickup forecast and ask for more rooms if demand rises.
- 14 days outFreeze the rooming list, finish name changes and reconfirm amenities and parking.
- Arrival weekShare arrival times and late check-ins, and make sure the hotel has the coordinator's mobile number.
Before you sign
- Force majeure. Make sure you don't owe anything if a hurricane or flood keeps your guests from reaching the hotel.
- Attrition basis. Hotels usually measure attrition by room night. Ask for it to count across the whole stay instead.
- Cancellation schedule. Group cancellation fees usually rise as the arrival date gets closer. Know what you'd owe, and when.
- Resale clause. It credits you for unused rooms the hotel resells. Many hotels won't sign one.
- Fees. Define or waive resort fees, facility fees and other mandatory extras in writing.
How it works on Engine
On Engine, you can self-book up to eight rooms. At nine rooms, Engine prompts a Groups request, and a dedicated team handles sourcing, negotiation, booking and management of the block. Complex programs and extended stays route to Groups regardless of room count. Once a block is confirmed, you invite guests, Engine walks them through booking their room, and you can see who has booked and who hasn't.
Questions
How many rooms count as a group booking?
It depends on the hotel. Engine's group rates guide puts the standard definition at a contract guaranteeing 10 or more rooms per night. On Engine, you can self-book up to eight rooms, and a ninth starts a Groups request.
What is the difference between a group booking and a room block?
A room block is one way to set up a group booking, with rooms held at a group rate under a contract. The other is suggesting hotels to your group and letting guests book their own rooms.
Can you cancel a group hotel booking?
Usually, but cancellation and modification terms vary by hotel and contract type. Fees typically rise the closer you cancel to arrival, because the hotel has less time to refill the rooms.
What is a comp room in a group booking?
A free room the hotel gives once a block reaches a certain size. Most hotels offer one free room for every 20 to 40 booked.
