I have a friend who has resisted for years (in her 30's) getting her own wheelchair. After a horrible experience at an airport, her husband convienced her that they should get a light weight folding electric wheelchair. She can now take her daughter to the zoo, where before she did not have the stamina to do so. If you are willing to invest in such a thing, it could help your daughter in more then just a disney trip, but open up more experiences in her daily life.
Orlando Medical Rentals has the most variety of small wheelchairs.I think we have her convinced to use a small wheelchair! Thank you all for the great suggestions Now to find a small wheelchair for rent.
