We have done several of these and while it was entertaining, there wasn't a lot of time to let the audience solve the mystery. There were a few spots where the audience had to mingle and ask questions and there was always something happening but it moved so fast there was no time for audience strategy, therefor any information collected didn't matter. At the end, they also gave just a few minutes to jot down your thoughts and turn it in to win. Other ones of these we have done were more about strategizing and solving.
Dinner was average as far as Vegas dinners go. A starter course of salad (mostly lettuce), chicken, potatoes and beans and then ice cream. Not the best but not the worst either.
Some tips, the game starts the second you walk in so pay attention. If you are a talker, please do not talk while the cast is talking, it's disturbing to the other guests, get involved. The cast does a good job of pinpointing guests who will be involved but don't be afraid to mingle and join in.
