The handling of negotiated (large) groups in the reservation process is significantly different from individual reservations.
Before any bookings are made by the group, there is a negotiation between the group organizer and the property, resulting in the creation of a contract. This process is completed well in advance of the planned arrival dates for the group.
Groups frequently involve special billing requirements, release dates for unused and unsold rooms, and additional contact and contract details.
At brand level, brand managers can modify, add, delete and view the groups belonging to all the properties to which they have access.
