DME to airport.... but not leaving MCO?

[SolPlyr]

We originally planned to be at WDW June 12-26. So, we booked everything and then got a rental car through Priceline. No problems yet, right? Well....... DW decided she wanted to go earlier, so we're now leaving on June 10. Not a big issue except that since I booked the car on Priceline, I can't change the reservation. And, I can't add a 2nd reservation and merge the two together; I would have to drive back to the rental car place, turn that car in, then go through the process again. We decided to take DME from MCO to WDW on the 10th.

So... here's the question -- Can I take DME back to the airport on June 12 (the original day of arrival) so I can pick up the rental car? Or, do I need to find another way there?

Taking DME back to the airport, you do not have to "leave town by sundown".

Members of the family can "go home early" via DME. Pick a flight, any flight, any airline leaving at about the time you want to be back at the airport. Remake the DME reservation for just you at least a day in advance of when it is needed.
