How do they get around at home? What type of assistance are you looking for? What issues might they have at an amusement park?
I'm a T6 complete paraplegic so my needs are different from someone who is a quadriplegic or an amputee or various other disabilities. However Disney does not provide any assistance inside the parks for me. All of my needs are mobility related so the
DAS isn't something that I would need. Disney doesn't push your wheelchair around the park or lift you on and off of rides so I have to do those things myself.
For Disney hotels and transportation Disney does provide some special services. When I make my hotel reservation I make sure I have reserved a roll-in shower room because I can't easily use a tub. When I book my Disney Express to and from the airport I make sure they know I have a wheelchair and will need a lift equipped bus. When I travel between my resort and the parks I use the internal Disney bus transportation and board from the wheelchair boarding area and use the ramp into the bus and the wheelchair tie downs.
