I have used a towncar, rented a car, Mears shuttle and have had a family member pick me up at the airport. I love the towncar but it is expensive for one person, with Mears my only complaint is they pick you up so early to go back to the airport--I have been picked up as early as 4 1/2 hours before the flight and this was way before 9/11, having a family member pick me up is nice but not always available. I have found renting a car for one day to get to WDW and one day to get back to the airport works very nice-if I pick up the car at 10:00 AM on the way to WDW I have the car all day and night before I return it and then on the way back I pick up the car at 4:30 PM and have the car all night and all the next day and then leave for the airport when I want to go. It costs about $25.00 a day which is less than a towncar but more than Mears but I can stop at the grocery store, outlets, offsite dining places, go to Universal or Seaworld the first or last day, etc. I rent from Dollar at the airport and then return the car at the Courtyard by Marriott in Downtown Disney, on the return trip to the airport I pick up the car at the Courtyard by Marriott and return it at the airport.
