Sorry or sadly have to agree with Disney on the golf cart issue. My stays this past august and especially October there were WAY too many golf carts it has become a safety issue. It was especially insane in October I am surprised nobody got seriously injured. I would say if you really want a golf cart then bite the bullet and reserve from Disney or buy a used one you can get aused cart fairly cheap it may not be the prettiest but it will get the job done. After 2 visits it would be paid for compared to golf cart rentals. October traffic jams of golf carts all loops, children darting out unsupervised or no parent around. It was a zoo. It's just going to be a matter of time before something really bad happens, Disney has to get some control of this situation, and hope they don't stop privately owned golf carts from coming into the fort. Luckily my golf cart is street legal it is considered a slow moving vehicle we can drive on any road that is 35 mph or less either way I am fine with my golf cart.
If u can get an offsite golf cart go for it while you can. Good luck and have a magical experience at the fort.
