I second the eating around the world comment. You’ve gotta do it! The Moroccan food was our favorite. However, I recommend going on Misson: Space BEFORE doing so, no matter how strong you think your stomach is.
My favorite “Future land” spot used to be the Imagination pavilion, but the recent remakes of the Figment ride have been less than spectacular. They should have kept the old song, the old puppets, it was classic. After all, imagination is not really something that goes out of date.
After my most recent visit, my new favorite “future” pavilion is the Land of the Seas. Don’t miss “Turtle Talk” featuring the Finding Nemo characters.
