Animal Kingdom is a fun place to go. The park is also accessible. We went to Animal Kingdom on our last full day at Disney World. Animal Kingdom isn't as big as the other parks, but it's definitely worth seeing.
I noticed the park might have had more hills than some of the other parks. My wheels sometimes got stuck in the gravel. My wheelchair isn't the best for outside travels.
Favorites:
Lion King Show: Lots of music and dancing. It's a lot of fun. You might jump here and there, but it isn't scary.
Safari Ride: We had to wait pretty long for this ride, but it was worth it. They offer a wheelchair accessible van so you can stay in your wheelchair. It might be a little bumpy, but it's not bad or scary.
Tarzan Show: This show is on the loud side, but not scary. It's a lot of fun. The music is very upbeat and fun!
