619 Can I change the name on my reservation? 2010/10/05
It is not possible to change the name on a reservation after it has been completed. The name on the reservation must match the name of the cardholder of the credit card used to reserve the hotel. Please cancel the original reservation and make a new one.

Please note that even if you are cancelling a reservation to make a new one, cancellation fees may be incurred. Cancellation policies differ, so please be sure to confirm the cancellation policy of each hotel.
