For future reference for anyone with upcoming trips, Disney is not responding to faxed requests anymore. Due to the overwhelming number of faxes they have been receiving, the room assigners have been instructed to only attempt to assign rooms based on requests noted on your reservation given to CRO.
This information was shared by several friends that work the front desk at resorts.
I would not fax any requests, call CRO and have them add your requests to your reservation.
