How do payments work for groups?
For a reservation that includes more than one room, one of the rooms is assigned to be the ‘main room’ for the group. All payments are processed from the main room.
Billing items added to any of the rooms in the group will appear on the invoice for the main room during check-out (also when a payment is processed, or the reservation is cancelled). The balance for a reservation includes all the items for each of the rooms in the group, minus the payments processed for the main room.
