That's right.
On our last trip, we packed up early and checked our bags (our were exclusively carry-on, as well) with bell services at our resort (PORS). We went off to the Magic Kingdom for rope drop, and bade farewell to our favorite attractions over the next 2 hours. We were back at the resort well before noon (when our ME bus was coming), picked up our bags (don't forget to give the nice bell services folks a tip!) and caught our Magic Express bus to the airport for our 3:00pm departure.
When scheduling your final day, keep in mind that if you are taking the Magical Express bus, it will pick you up about 3 hours before your scheduled departing flight. That seems like a long time, but by the time our bus stopped at a couple of other resorts, we got to the airport, walked across it, grabbed a couple of items at Burger King and got to the gate, we had less than 30 minutes
before takeoff.
