My husband has Parkinson's (not the shaking kind so it's not quite so obvious). Standing in a long line in the heat will cause problems for him. Also boarding rides like Haunted Mansion and others that move quickly is a problem for him. If I ask the CM to slow the ride for him to board will they do that? How about a waiting area where he would be able to sit while waiting his turn to board? Do we need any special paperwork about his PD?
