We are visiting Disney in December for the first time and are traveling with my 80-year-old mother-in-law who may need rest from standing in long lines or waiting for story tellers. My daughter read about folding canes with seats. Although I have read that you can bring canes on most rides, Disney lists that you cannot bring folding chairs into the parks. Would it be alright since it is on a cane? Does anyone have experience bringing canes on rides, especially this kind of cane?
