There is a shuttle service, you have to go down to the concerige desk the day before to reserve a spot on the shuttle. They will not allow you to call and reserve a spot you have to do it in person. The week we were there the open spots by the time I got there to reserve were for later than we wanted so we just drove since we did have a car. I would also look into the cost of a cab if you dont' want to be stuck with the return times
