Well you certainly have to work at Disney in my opinion with a wheelchair. After going with a broken foot a couple of years ago (yes, things seem to go wrong when we plan Disney trips..most often to me LOL!). I found most handicap parking to be worse than hobbling to the tram on crutches. It must be much much worse with a wheelchair...you don't have the choice of the trams. I didnt' find the handicap parking to be all that great.
In the wheelchair, people seemed to think we could stop on a dime, and we seldom went fast enough for the masses. When parked for a parade in a wheelchair, people figured I must have liked sitting down, and enjoyed looking through their heads. Forget going through AK and wanting to stop to enjoy the animals...once we were there, backing out was very trying. That time we did bring our own pass for our car..but this time around, I had no idea how sore I was goign to be after the plane ride..and since I thought I was feeling pretty good, we didn't bother getting one..which is why I called and asked about it. I'm surprised that since Disney runs it's own little city (without a school district) they couldn't decide to give out parking permits if needed. For me, the need wasn't dire, but for some, expecting to get one (in NY long term have them on their plates, not a hangtag, although I'm sure they could get one if they thought to ask a doctor to fill out the form), being told they could, that would be very troublesome.
