Has anyone rented a car from Disney while staying on site? I want to take a day trip to the beach, but do not want to rent a car for the 10 day trip. I would like to just rent it for the day. Has anyone done this? Is it difficult to do (a big pain in the tush trying to get the car and return it)? Suggestions are appreciated (P.S. It will just be DD (7) and I, so we do not need a van or anything special).
