We enjoyed our experience for the most part - however, one of the locks was broken. Every person in our group tried the lock with the correct code repeatedly, to no avail. We spent about 7 to 10 minutes on this one stage. It was then discovered the lock was malfunctioning. While we were evidentially given the information contained with in the lock by the staff; there was no accommodation made for the time we lost due to the malfunction. As a result of the lost time, we did not win our adventure. Had there been a time accommodation we would have won our adventure. As it was, we were within moments of completing our task. I understand that things happen, batteries fail and locks get stuck - however, those monitoring our adventure did not intervene in a timely fashion.
