Do you mean a motorized chair to get around? If that is the question, I would call the park..it seems like I have seen motorized chairs for people who need them.
We only went to the amusement park side. There are plenty of rides for different ages.
The big waterslides can seat a lot of people, and some other rollercoasters and rides like that can seat a lot as well!
Watersides and Rollercoasters, plus all sorts of other fun rides.
