Hi Treloarf!! Well be sure to tell the National Agent at the airport that you would like to drop it off at the Dolphin Resort - which is on Disney Property. We rented a van for 1 day about a week ago and were able to do this. My DH signed a paper to verify we were returning the van once we arrived at the Dolphin. We had a Bellman offer to take us back to our Resort (PO-Riverside) for a small charge, which I am sure he probably would get into trouble for doing. But everything was OK (w/ our bill) and we got back to our Resort quickly, as we were tired. But he was explaining that we would beable to get back to our Disney Resort using buses. At least one or two changes on buses though. Sorry, I don't remember what he said, but I know there was a way to get back to the Resort on buses. Hope this helps!! Good luck!
