My sister would love to go to WDW. She is 30 but has been in a wheelchair since age 14. Her health has been getting worse lately and it has been her dream to go to Disney. She cannot move her legs and has limited mobility in her arms. Additionally her joints are contracted in her knees and hips so that she cannot bend her knees. This means that her legs do not bend at a 45 degree angle. She is only 5 feet tall and her legs are very short but they will stick out a bit more than a usual person in a wheelchair because they cannot bend fully. She fits in the wheelchair lifts in the vans we take to doctor appointments- does this mean she will fit in the buses w/ wheelchair lifts at Disney? Are they standardized? What about the monorails? I'm also concerned about her ability to get into a plane. Any info would be great. Are there stations to fill oxygen tanks at WDW? She needs to be on oxygen at times due to lung probs. I would love suggestions on good hotels to stay considering our situation.
