A contact may wish to add or remove a place from their booking. One thing to be careful to check when removing a place is whether or not a payment has been made for the booking. If a payment has been made on the booking a place may still be removed, however, the amount paid will remain unchanged.
Removing a paid booking place does not automate a refund process. In order to refund the booker part of the payment amount you would need to cancel the entire booking, refund the contact and re-enter the booking.
