My stepdad, who has limited mobility with a walker, will be joining us on our upcoming November 7 day cruise (Western Carribean). The plan is to rent him a scooter that will be waiting for us when we board the ship. Anyone out there have any experience with a scooter on a Disney cruise? Specifically, was wondering how easy/difficult it will be to maneuver in and out elevators and cabins (will the scooter even fit in the cabin? we booked a handicapped accessible cabin); are the waits for elevators very long; are any of the pools zero entry or handicap accessible; leaving the boat at ports of call or participating in excursions; wheelchairs at Castaway Cay; etc. TIA.
