DH is on oxygen and can only walk a very, very short distance. Once we are on board DCL at Cape Canaveral should we immediately go to guest services to request a spot for golf cart service that is being offered to get to the island at LP? Or will we have to wait until we start to sail? We would like to go to the island as early as possible, to avoid the heat of the day as it effects his portatable oxygen equipment. Any tips?
