I have not had good luck with getting Club Orange when it was full. I would be tempted to cancel the one room and only book if two spots were available. You might have trouble doing this because I think you are not able to cancel Club Orange once you book. But, they might make an exception in your situation. If you decide to keep your Club Orange reservation, I would check with them on a regular basis because I wouldn't count on them calling you if a position became available.
