My DS will be in a wheelchair when we go to WDW due to a broken leg. We will be bringing his own wheelchair from home. My question is - will he be allowed to transfer to a regular seat on the buses? Can I just fold up his wheelchair and hang onto it? He doesn't need to be in it on the buses, but we will need it for more than just the parks, so renting a wheelchair from WDW is out. I'm just not sure about the rules with wheelchairs on buses, but I know he's rather avoid staying in the chair if he can.
