Skeptical visitors quick to find out why.
It's called Terror Behind the Walls. The attraction takes place in the massive castle-like walls of the historic Eastern State Penitentiary in Philadelphia.
Action News joins the Brown family as they toured the attraction for the first time.
"Just for the excitement and the thrill and to find out what the excitement was about," said Robin Brown.
Robin's daughter is eager to see what lurked inside the walls.
"I want to see my reaction. I feel like I'm not going to be scared," said Raven Brown.
This year, there are six thrilling attractions with new interactive experiences if you're brave enough you can opt into.
Those that do, will find themselves in an experience that can find them being pulled into dark passageways and even separated from the group.
The Brown family opted in. All made it out, minus mom, Robin.
"Unfortunately, our other friend didn't make it all the way through. She was too scared she had to get taken out," said Yasmeen Williams who was with the Brown family.
"My heart is beating fast, people touching me," said Raven Brown.
The question is, can you make it through?
