We stayed on the second floor in one of the newer OKW buildings with elevators in March 2001. They knew we had a person in a wheelchair because it was printed on our reservation confirmation. In addition to DD in her wheelchair, we had my FIL, who has trouble with stairs because of bad hips and knees.
What drusba posted is pretty much what we were told by CMs while the new buildings were under construction. It was "Disneyfied" a little, "We are putting elevators in those buildings so that our guests in wheelchairs and with disabilities can have the ability to stay on more than the first floor."
There are people who need first floor rooms that would have problems using a fully handicapped accessible room. For example, when we first started going to WDW with DD and her wheelchair, she was only 3 years old. We tried a wheelchair room, but with the raised height toilet, it was dangerous for her to use that bathroom. She's 16 now and is just about 5 feet tall if we stretch her. That type of toilet is too high for her to use still. It's enough stain on us to have to use them in the parks restrooms. By the time we get back to our room, I don't want to have to worry about her falling off.
To answer a few questions that were brought up earlier, we have been told that:
1) If someone requests a fully handicapped accessible room, it is guaranteed. The assumption is that person would not be able to use another type of room. I have heard of people being moved to a handicapped accessible room in another resort if all at their original resort were filled.
2) Requests for first floor for medical reasons are filled before other first floor requests. They are not guaranteed, but are almost always filled. If you need first floor, check your confirmation sheet. If first floor is listed, but not the medical need, call back and get the medical need added. One time we ended up on 2nd floor when we didn't have medical needs on the confirmation. We came in after midnight and were told that was all available. We carried DD upstairs that night (she was only about 8 years old) and the next day they got us a first floor room without charging the room change fee.
3) Requests for medical or handicapped accessibility made through WDW RESORTS/SPECIAL RESERVATIONS at (407) 939-7807 [voice] or
(407) 939-7670 [TTY] are guaranteed (from what I'm told). You can deal with them for all the resorts, although we have been told that
DVC Member Services will provide the same service.
