Room Availability Guarantee: is available only when the Elite member is the registered guest. Room availability guarantee is offered up to 72 hours prior to check-in for an Eligible Stay, calculated from noon local hotel time, subject to availability. Room Availability Guarantee is for Elite member’s personal guestroom only, for a standard room at standard rates, and is subject to the hotel’s standard guarantee and cancellation policy. Room Availability Guarantee is not available for reservations for Award Nights or Points + Cash nights, is not available ... when a nationally or internationally recognized event is occurring within fifty miles of a participating hotel (as determined by Club Carlson).
Eller med andre ord: Den garanti kan hotellet nok altid smyge sig ud af.
Jeg tjekkede også Marriot Rewards. Her kan jeg ikke finde det, der står med småt.
