We will be staying in St John the 3rd week of June and plan on renting a Jeep. (Yes , I know, we need to reserve one now:) Can anyone tell me if there is an advantage to renting a Jeep in St Thomas then taking the car barge to St John? The only thing I could think of was maybe grocery shopping in ST before we went over and also on the trip back shopping a little in ST before we turned the Jeep in. Our flight going home leaves at 4 so we would have a few hours to kill. Our Jeeps less expensive in ST?
