Powered chairs are allowed but are not available. Standard wheelchairs are available in the entryway. There is a tram that gives you an overview of the sculpture park. The tram runs April into October. The tram station is a bit of a walk from the entrance.
No, but the do have a trolly that drives people around outside for scuplture viewing it does cost money. (and plenty of traditional wheel chairs for in doors)
I don't believe they do.
