This is a semi-serious semi-non serious question that was in my mind. We all know both Disneyland and California Adventure are starting to become quite cramped and things would have to be demolished in order to expand. That hotel building behind Carsland, the Submarine Lagoon, and surrounding commercial and residential zones...all would have to come down sooner or later in order for that new ride, land, or park to exist. My question is could Disney go down? Down into the ground that is. Right under the parks in order to make a new land. As ridiculous as it sounds, could it work? I mean, avoiding all the underground pipes and being deep enough so the roof won't collapse above you.
I am no engineer and I can still see problems (Roof cave in, underground obstacles, cost, OSHA, etc.) could an underground land work? Or is my mind just being fanciful again?
