A group from work came here for a team building exercise. Half of us participated in the Shipwrecked experience and I was apart of the group who did the Residents. Our group had a lot of fun! The puzzles/riddles were much harder than expected, and although we did not escape the room within the hour we made it a little over halfway (I would think!). Some people in our group are already planning to return with their families.
My only recommendation would be to bring a flashlight and reading glasses if you have bad eyesight. This is also not a good activity for germ-a-phobes. I didn't find it as scary as some people may think it could be.
