This is a great evening out activity. One of the great advantages is that you can go with a group of up to 12 friends. I went with 4 friends (two couples). We played the Escape from the Tower game with 2 other groups of 4. It worked out really well. There were opportunities for everyone to be involved, which I had wondered about. The balance isn't always perfect (e.g. for one activity there were only two special lights to look for a key clue), but this company has done a great job of creating a good experience.
I'll definitely go back, and tell others it's worth it!
