Participants must register at least 24 hours in advance, either as an individual or as a group of four to eight people. Individuals should know that if the escape room doesn't have at least three other people for the assigned time, they will have to reschedule..
Why the sudden popularity of escape rooms? Vaughn believes it's because escape rooms are more engaging than "going to the movies on a Friday night."
"This is a chance to build your own mystery, find out your strengths and weaknesses with riddles and puzzles and work as a team," Vaughn said.
For the record, the name Mercy Madmartigan is completely fictional, Vaughn said. Vaughn liked the juxtaposition of the first name with the character's acts. The last name was inspired by Val Kilmer's character "Madmartigan" in the 1988 movie "Willow."
"I just loved that movie," Vaughn said.
