Cleaned up ? charged ? Maintenance ? what are these things you speak of, none of which I have ever found related to a Disney cart. The LAST (and I mean last) cart we rented was low on charge, dirty and if you let go of the steering wheel it would be in the weeds within 50 ft. (took it back and all I got was a sorry we are sold out)
After that I either bring my own (no longer practical with a 5th wheel) or we just bike it.
