10. The entrances/exits are hidden in plain sight.
The utilidor system spans almost the entire Magic Kingdom, and there are many entrances and exits throughout the park hidden in plain sight. You have probably never noticed them, but once you begin to look for them you can see them in plain view. Generally, the doors are typical looking, unmarked doors. Each door is painted either to blend seamlessly into the land it is in, or it so completely drab that it is barely noticeable.
