The guarantee is, not a real guarantee. Nothing at Disney is, such as medical NS, etc. They don't block rooms when you book them. So when you book has nothing to do with guarantees.
If your confirmation says "Guaranteed handicapped" or "Guaranteed wheelchair accessible" or "Confirmed Wheelchair accessible", it means just that. It is a guarantee and not a request.
A person who needs a wheelchair accessible room can typically not stay in that resort
unless they know they will have a wheelchair accessible room.
When you make a reservation for a wheelchair accessible room, before taking your reservation, they check to make sure one is available for that time period. A room is blocked off at the time of your reservation and that particular room is reserved for you (they won't tell you what room it is, but is blocked). So, it is guaranteed.
But, things can happen - such as a handicapped unit going out of service. If there are others of that size available, they will just move you to another that is available and you will possibly not even know it happened. If there are none of that size in the resort, they will move you to another resort.

Someone can correct me if my memory is failing, but I think there are only a very limited number of handicapped GV's -- I think it was one before they built the new buildings. If something has taken one of these out of commission, that would throw everything off.

You are exactly right, Pam.
My guess since it is only 3 days before your arrival, is that something happened to make the GV that was blocked for you not useable. There are
only 2 handicapped accessible GV at OKW, so if something happened to one of them and the other was already guaranteed for someone else, they don't have a place they can put you. (One is in building 63 and the other one is unit 4815.)
The wheelchair/handicapped accessible ones have roll in showers, roll under sinks and grab bars in the masterbath and a roll in sink in the kitchen. The rest of the unit is the same as all the other GVs. If she needs a roll in shower, you are out of luck at OKW.
I believe there is only one other GV in building 63 (but Doc probably knows for sure). If she doesn't need the roll in shower, it might be possible for them to agree to block that one for you (but, that's a long shot, since it might already be occupied and they won't move someone to accomidate you). You can access the GV in building 48 and the ones in building 63 without going up a flight of stairs, but all the others begin on the second floor.
SSR has elevators in every building, so if all you need is to be able to get into the GV, you could use a non-handicapped one there.
