Not a bad price depending on how many days that is for, however For the extra half hour (MAYBE) I wouldnt bother. DME Is pretty unique in that it allows you not to have to get your luggage on your wayinto the World!!! Id give it a shot. As far the extra half hour, you would then have to allow time to drive to the rental car return site & return the car, if it isnt at the airport you would have to allow time for the shuttle to get you and luggage back to the airport. Trust me it will be a few minutes difference at best. If you prefer to have the car for other things such as shopping or dining outside of Disney, that I understand. To rent it specifically for the trip back to the airport?? I wouldnt bother. Belle
