FWIW, and I hope it's current:

RITZ-CARLTON HOTELS

Reservations: 1-800-241-3333

Specify the Marriott Rewards certificate Reward Code when making reservations. A guarantee to your credit card is needed to hold your reservation. Cancellations must be made seven days prior to arrival, or a cancellation charge amounting to the sum total of one night's published room rate will be applied to the member's credit card.


Certificates are not redeemable for cash and will not be reissued if lost or stolen

All Ritz-Carlton locations participate in Marriott Rewards hotel rewards as a redemption option. For a list of Ritz-Carlton hotel locations, visit
