If you are planning on using the buses to get around, I would highly recommend an outside rental of a wheelchair. There may not be seats on the buses when you arrive, so you either wait for the next or stand. If she has a wheel chair it's a guaranteed seat. Also I do not believe your group will be permitted to just sit on the ground. It can be dangerous in crowds as you are now a tripping hazard. Given the crowds at this time of year, there is no real out of the way place to sit.Ok. I guess that I'll have her leave it at home then. I don't want to drag it down there and her not be able to use it.
If I can talk her into a wheelchair and there are any even available, we will go tat route. If not then she will just have to sit on the ground with the rest of us.
