Wow! This was so much fun! It was our first time ever going to something like this and our guide Casey was very helpful and accommodating. There's an hour time limit and when we timed out, she allowed us to stay longer until we made it to the end. It was a great experience! We started with the moderate level of difficulty. We needed a couple clues at first, but eventually figured things out. We'll definitely be checking out the other rooms when we come back to visit Vegas.
