Overbooking is a situation in which more room reservations have been accepted by a hotel than the property is able to accommodate. Hotels use historic no-show information to determine what percentage they can over-commit rooms. This practice is intended to enable 100\% occupancy for the hotel.

Hotels that use overbooking as a policy are increasingly being targeted by tour operators and wholesalers in an attempt to better control and minimise the serious adverse marketing effects which overbooking has for all stakeholders.
