Very clean, friendly environment! We have been to 2 of their rooms and loved them both. They will help you if you're super close to solving a step. A couple of the steps are a little glitchy, so if you're sure of an answer, try it a couple times (flipping switches don't always engage). We had to have them manually open a door because we were entering the right code but it didn't engage after several tries. But they are watching the whole time, so they don't let you lose time. The games themselves are some of the best we've done with great thinking/deducing that has to happen. Even with the glitches, definitely worth checking out!
