Wonderful experience! We did Top Dog! Great fun once we got the hang of it! I got a Groupon so we could try it out. Well worth it. I would recommend at least minimum 4 people to solve the mystery. It was just two of us, my 13 yo daughter and me, and if you don't really know what you're doing, it makes it quite a challenge. Time was up when we had 2 clues left. The more people you have, the better you will do. But, I would highly recommend! Staff was also very helpful and friendly. Guy at the front desk was super nice and even let us stay in the room after to finish the last 2 clues. I want to go back with more people and try the Whimsical Library!
