It probably would have been easier to do this through reservations, but I think it's too late. They could have simply "linked" your two reservations and made a note to keep the rooms together. Chances are, your friends reservation has already been downloaded to the resort and yours will probably show up tomorrow. I'd wait until Thursday afternoon or Friday morning to send the fax. You should only need 1 fax, just note both reservation numbers and the names on the reservation. I would ask them to link the two and keep you in the same area. Let them know that you'd prefer one of the following 3 buildings, but your priority is to be close together.
