I know that a lot of people have heard that Disney is enforcing the ADA guidelines for a "common wheelchair" when loading scooters/ECV on the buses. Hopefully this post will clear some things up: What size is allowed? The maximum size allowed on the buses, as defined by the ADA is: 30 inches wide by 48 inches long. This size MUST include all baskets and bags, according to the policy. Why are they doing this? This is for safety reasons. For a scooter to be safely tied down on the bus, it must be able to fit into the designated space on the bus. The buses were designed according to the ADA guidelines, which states the largest size for a standard wheelchair (i.e. the largest size that the bus must accommodate) is 30" wide by 48" long. This is a picture of the box being painted on the ground at bus stops. It is 30 inches wide by 48 inches long from the outside of the white line on one side to the outside of the white line on the other side. What about the companies listed in the FAQs? Apple Scooters: All scooters will fit. Randy's Mobility: They do not state it specifically, but judging by photographs and the models they do say they rent, all scooters will fit. Walker Mobility: They do not state it specifically, but they appear to use only Pride products, which means all scooters will fit. CareMedical: They do not list the manufacturers of their scooters. Buena Vista Scooters: All scooters will fit. Scootarama: All scooters will fit Scootorlando: All but the Dream Scooter should fit, though they do not give specific models. I know that their website says that the Dream will fit, but per a Transportation CM here on the board, bus drivers have been instructed not to load them, and the company has apparently been notified. So what does this mean for me? It means you should CALL YOUR COMPANY when you make a reservation for any of the larger/heavy-duty scooters and ask what models they use. You can find dimensions for any scooter online. PLEASE double check everything I have said here. What I have said is not a guarantee, and you should always double check with the company.
