12. It’s actually not “underground”.
This is a hard fact to wrap your head around, to be sure. The utilidors are not underground at all; rather, they are truly the “ground floor” of the entire Magic Kingdom Park. The area that we enjoy was actually built as a second floor on top of the Utilidors. In fact, cast members who are bussed in to work at the Magic Kingdom enter the utilidors from parking lot level, just as you and I would enter a tunnel through a mountain in our cars.
