They will have them at the beach stops. So you have to walk down till you get on the tram and then the first or second stop (for the family beach), and then go to the rental place at the beach (we always go to the second stop and see them by the cabana check in). They will let you leave your wheelchair there. They are limited and first come first serve. They can be difficult to use in the sand. We have found taking them backwards is best.
