This is not actually I. The park and I am sure anyone can do it, but tour the grand hotel. I believed it is a4 pm. Also if he is getting hot and needs a break, depending on where you are staying, the grand is a nice place to stop. My sister was in a w/c growing up and one of my parents use to slip into the grand lobby for a few hours to give her a break, she could slide out of her w/c and get off the hard plastic seats that made her legs stick. They use to have a story time inside the little alcove, not sure if they have that anymore. They also use to have a piano player so you won't get to board. Mom use to let us get drinks virgin of course from the lounge and we would just sit for an hour or two.
Another place my sister loved but my mom did not, was the water play areas, my sister would get right up to the water and throw herself out of the w/c and play for hours in the water, on the ground. Mom eventually gave up telling us no. There is one at bugs land enterance I think, they use to have a daisy bout or something but I don't remember seeing that lately, maybe it's not there anymore, it was over by the jumping jelly fish and the swings I thought. They use to have one in DL also, where the big wheel is in front of space mountianerr, but I'm not sure that's there either. Boy it's touch to grow up, you forget what fun you use to have, now some off he things are gone I think.
The one last thing not mentioned here, I think is lincolns great moments. Nice place to cool off.
I can't imagine not liking rides. We did, but I do remember we always had to spend an hour or two letting my sister move around outside the w/c, so her legs, or butt would not get sores. She wore leg braces also. My boyfriend was in a w/c but can stand up and move around so he doesn't have problems.
If I can think of more I will come back and let you know. Oh mom always let us get into the hot tub at the end of the day she always told my sister it was good for her. Also, we went swimming. My sister has cerebral palsy, she can walk, now. But she was in and out of w/c from 2 to 12 because her hip kept getting pulled out of the socket. She never had surgeries but she had cast and braces that made it hard for her to walk also. also the w/c came around and held her back in a position, because her back started to curve, so once in the w/c she could not move easily, so every few hours mom gave her a break.
