Went with girlfriend and another couple - absolutely fantastic!!
We had no idea what to expect, it was our wild card activity for the vegas trip and ended up being everyone's favorite part. They feed you, beer you, and several of the cast are down right hilarious. Definitely recommend it. My only concern is apparently they have recently changed it so that there is less walking. There wasn't much walking to begin with and I think that scavenger hunt element was key for the experience. Hopefully a few olds and fats complaining about walking half a mile doesn't ruin the experience for everyone else.
