It shouldn't be a problem, especially with a note from her doctor and a GAC. Can she walk a little and put weight on her foot? Many rides require getting out of a wheelchair ( in her case the stroller) and boarding the ride vehicle. If she can't put weight on her foot, you will need to either lift her or get her some crutches to bring with you. I have recent experience with this kind of dilemma. My 16 year old DD tore her ACL this June the week before we left. She could not put any weight on this leg. However, with her crutches, a wheelchair (transport type) from home, a knee brace, and a note from her doctor, she was able to enjoy every ride and we had a great trip. She just had surgery yesterday and is doing well. The folks on this board were really helpful with all my questions, and I will be forever grateful.
