The whole problem with all of this talk about Toontown is that you are now approaching the fireworks zone. Disneyland would not be able to do big fireworks shows. Toontown is mostly buildings and cement because of the falling fire coming down on it every night. If you want to expand Fantasyland it would have to be a pretty empty place with just buildings because you really can't push the foliage any farther back. Also being able to close a whole land makes more sense than closing off a portion of land every night for fireworks.
