Well I am back from Disney, and I did pretty well! Don't get me wrong, I was suffering on and off, dearly, but I managed. I got one of those Guest Assistance Cards, but like another Poster, there weren't many times where I had to use it, the crowds/lines were very light.
Also had my 3 legged cane with seat and that helped a great deal. It was very interesting, not one person offered me their seat when I had to stand, with my obvious cane. I even had people trip over my cane and give me a dirty look, like it was my fault, and no "sorry/excuse me" (that was disappointing).
Florida had a heat wave the whole time we were there, oh well. Also, my husband came down with flu-like symptoms that turned into bronchitis. So for the last 3 days I was on my own with the kids. The best laid plans of mice and men.........
I was very pleased with Disney's help. If you are ill you can have them drive you to Urgent Care and return you back to your hotel. They are also extremely helpful to anyone with a disability. I was very impressed.
All in all, whatever pain and discomfort I had to deal with was worth it to see the look on my kids' faces, and at the end of the trip when they thanked me for planning such a great vacation, it put a big smile in my heart.
