If you book online, you are booking through WDTC. I took the following from Deb's site.
A CRO room only reservation requires a one night's deposit within 14 days. If arrival is less than 30 days out, deposit is required at booking. The balance is due at resort check in. MasterCard, Visa, American Express, and Discover are accepted. You may also mail a check or money order. Cancellations up to the 6 day mark will have your deposit refunded in full. Cancellations after the 6 day mark will be charged the one night's deposit as a penalty. Any additional amounts that may have been paid on the reservation will be refunded in full. There is no time limit on when you can make modifications to an existing CRO reservation with no additional charge. This can be done right up to arrival.
A WDTC package (including the "room only" Basic Package) requires a $200.00 deposit within 14 days of booking. The balance will be due 45 days prior to check in. Checks, money orders, MasterCard, Visa, American Express, and Discover are accepted. Cancellation between 6 and 45 days prior to arrival will result in a $100.00 fee. Cancellation 5 days or less will incur a $200.00 fee. Any change or modification of the reservation inside the 45 day mark will incur a $50.00 fee.
