My mom is disabled and very sensitive to being jostled or rides that jerk her around too much. When we go my dad stays behind her and I stay in front of her and keep anyone from bumping into her, but we also use the train a lot to get around rather then walking. It turns out that most of the rides are pretty bumpy. She pretty much only does the shows, the train, Mansion and Soarin. She used to be able to go on Pirates but for some reason the load / unload area is crazy bumpy now. So I'd say maybe this is a good time to focus more on the ambiance and enjoy some things you've never seen before, like some of the live music (esp. New Orleans Square) and entertainment. If you're going to try to see Fantasmic I'd for sure do the dessert buffet just so you don't get bumped too much.
