You might get more info on the Disabilities boad. Between my parents and my aunt, we've used Apple Scooters and Buena Vista. There are several companies out there and they are all pretty well rated. You want to look for the company that will take the
scooter to your hotel and pick it up (and meet you). Most will. Then you look around for the best price or deal at the time. We've had ZERO problems with either of these companies. At some point in 2019 I think Disney severed some of their contracts with the companies and kept one if you just want it delivered to the bellhop. Honestly, I haven't planned a trip there in almost 3 years now so I forget. But it's very easy. Again, head over to the disabilities board and you'll get lots of info.
