We loved the Crooked Key! Our group of four adults enjoyed the Old West room. It was just tough enough to stump us at times, yet we were able to finish with a few minutes to spare.
The next day we did Key to the City. This is definitely more of a scavenger hunt and we enjoyed it less than the escape room, but it was a beautiful day out and we learned a bit about Steamboat and the region. I'd say that Key to the City is best for families.
Overall, we'd highly recommend the Crooked Key!
