Staying at POR 8/20-8/25; however we will be flying into MCO a couple days early to visit with family that live in the Tampa area. We will need to rent a car for those couple of days. Once in Disney we don't want the car. So I'm thinking we could rent a car at the airport then on the day we're scheduled to check-in at POR return the car at MCO and take the magical express. Can this be done? Or does Disney only allow you to utilize the M.E. on the day you're actually flying in? Is there an easier way that I'm just not thinking of?
