Our friends daughter just broke her ankle one week before their trip. Many people have told her they will now get front of the line access -- which I told her was untrue. Would it be easier for her to stay in the wheelchair through the line que or to use her crutches? Can she be pushed in the wheelchair and get out and board the ride on her own and leave her wheelchair at that point? Any tips would be appreciated, I'm sure this has been asked many times.
