Like 30 to 45 mins. It's pretty long.
Once you get in, it's about a half hour. It is massive!
It is a good long walk/scare!
I would say about 30 minutes, but it all depends on the group in front of you and how fast the people you are with are moving through the rooms.
Yeah it was long tons of rooms
You can stay in the rooms for over an hour to complete everything.
