Faxes and room requests
In the past, the Walt Disney World Resort was receptive to guests faxing their respective resort and making special room requests. I myself would fax my resort at the proper time, exactly four days before arriving. The fax would start off very complimentary to the resort and then follow with my request. In some cases the request would involve a specific building, specific floor, specific view, or even a specified range of room numbers.
Unfortunately, some of the resorts have discontinued this practice of taking requests over the last few years. All is not lost, however. If you wish to make specific room requests, my suggestion is to do so at the time of your booking. The resort you are booking with will receive this information along with your reservation. I have tried this and it seems to work. After all, first-come, first-served.
