My other half and I did the "Kiss of the Dragon" room, and it was very imaginative. We were constantly using our wits to race against time (60 mins total).
The key is an attention to detail, and we found that we could've paid more attention. But we enjoyed the challenge very much, and the people running the place were OK with giving us that "vital clue," one that would help us win the challenge.
We would very much recommend the challenge. Take the plunge and you won't be disappointed. It was a unique and rewarding activity!
