Trivia

 * Wonderland and Deep Space are the only Disney-based worlds that are not set on "Earth". Halloween Town may or may not actually take place on Earth because in the movie The Nightmare Before Christmas, Jack is seen to visit the people of Earth and is attacked by the U.S. Army. However there isn't enough information to draw a definite conclusion on where it actually takes place.
 * Deep Space is now the only Disney-based world that is not based on the main setting of its film. The main setting would be Hawaii, which does actually appear in Stitch's summon sequence in Kingdom Hearts II. Neverland was once a case like this until Kingdom Hearts 358/2 Days, in which parts of the Island itself are explorable.
 * Deep Space is one of the few worlds to not actually be a world. It is a large spaceship capable of traveling to other worlds.
