This was our first escape and none of us were sure what to expect going in. We had an age range of 6-60 and everyone seemed to enjoy it. The 6 year old is kinda a chicken so she had some moments, but other than that, it was fun. A nice change of pace from the usual. Puzzle was not too easy and I'm sure if it had been 6 adults we would have figured it out instead of constantly trying to pry flashlights from kids.
The only suggestion I have is as this place grows and expands, to incorporate more of the senses. A little more of that and ross place would be beyond awesome. Some smoke, creepy music, etc etc.
We all loved it, and even those who normally avoid participating in things like this, thought it was a good time.
