Personally, I think faxing the room controller is a waste of time anymore. I'd just be sure that any big requests (non-smoking, connecting rooms, etc.) were noted on my reservation and not worry about the fax.
Thank you for the number. I'm not sure if I requested ground level (which is important to us) on my reservations. Is it too late to call CRO? I wasnt sure when the res is sent to the resort.
