First, DWofjdads2, here's some pixie dust for a great trip. Remember to use the in-park transportation rides, like the train at MK, Friendship boats at Epcot, etc. They can save your feet a lot. If you need to sit and put your ankle up, First Aid can be helpful.
I cannot believe that people actually gave you a hard time about your cast!
I can believe it because we have overheard people making rude comments saying that my DD is "cheating". She has a custom wheelchair that cost more than my first car, is permanently disabled, can't even stand without someone supporting her and never will. But, people who have never seen us before have commented to other people in their party that she must be "cheating" to get ahead in line.
There are very few rides/attractions where people using wheelchairs get any special treatment and it is basically because the lines are not wheelchair accessible. It's not a perk and often we have to wait longer than ambulatory people. Our longest wait was when we got in line for the Safari when the CM was telling people "No wait. Just wealk right in." That was right, if you could walk, you could walk right in. Trams were even leaving partially full because people weren't walking in fast enough. But, those of us waiting for the wheelchair car, had an over 4o minute wait. People asked about going in the "regular" car, but since it doesn't exit at the same spot where you get on, they wouldn't let anyone who had a wheelchair or
ecv do that.
And, I agree that the handicapped parking is quite a trip to the park entrance. If you have a wheelchair and need a bigger parking spot, it's helpful to park there. If you are driving and renting a wheelchair or ecv at the park, you are usually better off asking the parking CM to let you park at the end of a row near the tram stop. That really minimizes walking. There are no trams to the handicapped parking lots.
