Do you mean to get around the resort area? Yes, they have complimentary cart and van service that goes between the Cove, Reef, and Morningstar resort areas. Ask at the front desk for where the pickup/dropoff is and schedule. If you walk between the resorts, there are steps and some steep hills.
There are elevators available in the Cove buildings, and the walk between elevators is relatively flat so its easy to get from a higher building down to the pool/beach.
