FAST PARK AND RELAX just off the Service Road is SUPERB and only 7.18 a night....it is cheaper than taking the Villages Shuttle. You park your own car the shuttle picks you up at your spot and drives you to the terminal. GREAT company. When you leave, you get a cold water bottle. In the morning, they give you a free Orlando Sentinel also.
