We have a Wednesday, 12/15 flight out of MCO at 6:30 PM. I've reserved a car from National for our trip and assume I'll be driving back to MCO on 12/15 right in the thick of rush hour. Right now the car reservation is for pick-up and return at MCO. Given the time of our drive to the airport, would I be better off to return the car to the Dolphin (probably the afternoon of the 14th) and hire a towncar service for our trip back to MCO?
