Guaranteed Room Availability for Platinum members must not apply during special events that result in extraordinary room demand, as determined solely by the hotel. Up to 10 special event calendar dates per year can be designated in advance to the reservation system by the hotel. The member must not be charged more than the prevailing rate for the accommodation requested, and the member is not entitled to a rate less than the prevailing rate. Once made, Platinum Guarantees may not be dishonoured for any reason. If the member does not arrive and has not obtained a cancellation number prior to 18:00, the credit card must be billed for one night’s room and tax.
