I rented from National (in MCO) in Dec for Dis con and returned at the Dolphin. Its so easy to return at the Dolphin the desk doesnt even have to be open. I just drove up front and one of the valet guys came over to the car, checked the gas level and wrote on my contract it was full and off I went. I think I was on my way to MGM so I just hopped the boat and was there in no time.
