My mom is going to need a scooter on our next trip and I think we are going to try Apple this time. In the past when we rented, one of the scooters was almost too long to fit on the bus. Mom is a heavier person so she will need a heavier built scooter. Has anyone had trouble with Apple's scooters being too long or almost too long to fit on the bus or know what length the buses will accomodate so I can check? Thanks!
