You could save a bundle if you are willing to pick up your rental from an off-airport location. You can return the rental to MCO, but you must pick it up off-airport. There does not appear to be a premium for dropping it off at the airport, as long as you pick up at an off-airport location. I tried this on the Costco website. For Christmas week, the rates are cut in half when picking up the rental at any of the off-airport locations. You would simply need to take a cab over to your off-airport pickup location. Even factoring in the cab fare, it is still far cheaper.
(1/8 -1/23). Is your countdown wrong?
. You can also rent a car one-way from MCO for one day and pick up your new car near WDW the next day.
