I just booked a night at the Sheraton Montreal and chose a Club Floor room, which includes breakfast and hors d'oeuvres. It was $12 more than the cheapest, non-refundable internet rate available on SPG.com. If I cancel and re-book at the cheaper rate, will I get upgraded to the Club Floor room and get the same "extras"? Or should I keep the current rate and expect (hope) to be upgraded to an even better room?
