1. Processing delay: It takes a certain time for a bank to cancel the pre-authorization, generally ranging from 3 to 7 working days, depending on each bank and credit card type.
2. Unpaid bills: ensure that all payables, including accommodation, catering or other service charges, have been settled when checking out. If there are unpaid fees, the hotel can continue to reserve pre-authorization for settlement.
3. Hotel operation error: The hotel may have forgotten or delayed the cancellation of pre-authorization. At this time, it is suggested to contact the hotel front desk directly for inquiry and reminder.
