I took my husband for his birthday. There was a group of 6 of us. We booked the room called "the dig" which holds 10. It was a lot more challenging than I expected. We made it out with less than a minute to spare. Advice: you don't have to strong hand anything to unlock a clue. If something feels like you'd have to pry it open, don't waste your time (or risk breaking anything) and keep looking for the answer/clue.
