I'm heading back down to the World next Saturday and I'm taking my mom for her first trip! I have a FP+ for the Mine Train, but I'm a little worried now after reading something about people who are extra tall or a little on the bigger side just won't fit. Does anyone have experience with this? When I went on it in October I didn't notice since I'm 5'2" and fairly small. Should I change the FP? I don't want to get there and then not be able to go on.
