Vacation Planning Centers, Owner Website, CLUB WYNDHAM Travel and Financial Services Unavailable May 9 and 10
Providing exceptional customer service is our top priority. On Wednesday, May 9th and Thursday, 10th, we are relocating our data center and will be temporarily closed. During this closure, you will be unable to contact any of our service centers, log in or have access to information online, book, cancel or modify reservations or make a payment on your account. During this time, the CLUB WYNDHAM resorts remain open to welcome your confirmed arrival. If you have already booked travel that will take place May 9 through May 10 and encounter any issues, please contact the resort you are traveling to directly and they will be able to assist you. We appreciate your patience and anticipate that services will return on Friday, May 11.
