We check our bags with bell desk, check in to get notified when room is ready, and hop the boats to the TTC where we ride the monorail - it makes us feel like we're really 'home' again.
Don't forget to take breaks! There is a cool down area outside Test Track in Epcot. Hit the Character spot while in Epcot. I have the cutest picture of my son meeting Mickey for the first time from there.
