Our son will be in a wheelchair at Disney and we will be using the buses. I have been told that we will fold the wheelchair and keep it by us on the bus. Does that mean that someone should stand with it by the doors or would it work to have it in front of us? I am assuming it would be in front of 2 of us due to width. If we just held it close to our legs, does that work, or is it in the way of other passengers? I am a bit anxious about how this whole thing will work out. We rented a wheelchair for him last trip, but we rented from the parks so didn't have it on the bus.
