We typically take an evening flight home, so that leaves us with a morning/early afternoon to enjoy before we head back to MCO. We also rent a car and drive ourselves around. We check out of our resort in the morning, of course, and send our bags to the airport via Disney's airline checkin service. Which is awesome. Our carryons, we load into the car, and we're ready for the rest of the day.
Our now-traditional final park of the trip has become EPCOT. I know, I know, EPCOT needs attention - desperately. But there's still enough for us to do to make it worth one final visit before we head home. We hang out a bit in the land and seas pavilions (especially the seas - my son could watch the manatees for hours) and then we meander around the World Showcase, trying to catch any favorites we missed on earlier days. We try to make sure to FastPass Soarin' while we're at it - that's my son's most recent favorite. We eat a good lunch, usually table service, since we know that the food options at the airport are pretty cruddy. (Burger King. Not really our thing, but it's what's near our gate.) We always do Memory Maker, so we take time to have our pictures snapped whenever we see a Photopass photographer - last licks, so to speak. And the final thing we do is give our little guy a coin to wish on at the fountain. (He always wishes to come back to Disney World soon and do it all over again.) For us, it's the perfect ending to the trip.
