I believe this was one of the first escape rooms that my wife and I attempted after seeing what an escape room could be, and we were in for a surprise. This was back before The Great Escape Room began labeling their rooms of different types, so this would later on be knows as a Puzzle Room, or Scavenger Hunt room, and will forever go down in infamy as being the room that forces us to ask the question "Does your room include puzzles that require you to disassemble any furniture, or remove any grates from the walls?"
The room itself is rather large, and you have a game master in the room with you at all times to assist with finding puzzles if needed, if you find yourself stuck. This is a larger room that really requires more then two people, but can be done if you're on your game. The puzzles don't have much to do with the room itself, and can sometimes be misleading with how they're supposed to be accomplished. There's less of a focus on actual escaping, and more of just "Get the puzzles done in this order, and make sure you have each clue from 1-5 to have all the info you need."
We didn't escape this room, but I think it was more because we were so fresh to the escape room scene and didn't know how to think about what an escape room could be, then the room itself. I can't recommend this room for any groups smaller then 4 people, and would say that if you're a vet of the escape room experience, maybe look at some of the other offerings that The Great Escape Room may have available!
