My mom injured her knee and is therefore renting an ECV for our upcoming trip. She is renting from an offsite company so that she has it available all the time, and we will have a rental car to drive to the parks. Obviously we can't get the ECV on a tram; do we need to have a special parking pass or doctors note so that we can park where we do not need to use the parking lot tram? Obviously I have never been in this situation before, and we really would prefer not to take the bus since we always drive to the parks. Thanks for your help!
