We did the same thing. My mil lives in tampa. We stood one a week in tampa and then drove our rental to our resort. Dh then drop me and the kids off and then dropped off the rental @ mco. Be careful because we verified that we could do this before we left home and then when we got to our resort called ME and they told us if we weren't arriving by plane that day we(dh) couldn't use ME. We weren't happy t o say the least. So dh said I will just have to take a taxi back but something told him to go to the ME counter and try. Guess what? They took him with no problems. Just have a back up plan in case this happens to you too and even if they say no over the phone. It can't hurt to give it a try once you get there. Sad to say you can't get a straight answer..
