The best time to make this or any other room request is at the time you book your stay or as soon after as possible. All request made to Central Reservations are time-stamped to aid the Resort in room assignments, which are done about 1 to 3 days prior to your arrival. Any faxes or direct calls to the resort itself for room request will not be accepted.
Of course it doesn't hurt to ask again when you check-in if your request can be honored. :animwink:
