After you defeat Adam the clown and stop the roller coaster, a Willamette employee will be on the ride. His name is Greg Simpson, and he will tell you he knows a shortcut back to Paradise Plaza. You will follow him into the women's restroom, where he will stand near the sink and say "Go right through here and you'll be in Paradise Plaza". It is difficult to understand what he is talking about. Jump up on the sink and an icon will appear that reads "Paradise Plaza". You now can simply leap back and forth from the women's restrooms in Paradise Plaza and Wonderland Plaza. Not only is this a useful shortcut, but it is also quite helpful in getting survivors back to the security room safely.
