I hoping someone can help me here. We are going to Disney in two weeks and I have injured my knee and can only walk very short distances before it swells and walking becomes unbearable (dreading the plane ride) - changing our plans is not an option as this is a trip with my brother and his family and trying reschedule would be a nightmare. I hope with lots of RICE I will be in better shape before we go but I am wondering if wheelchairs or electric scooters are available should I need one? Do you have to make arrangements before you go? thanks.
