Went to Xtreme Escape on 4th of July with my family (including 90 y/o aunt). Everyone loved it. We had done another escape here in Las Vegas, so we had an idea of what to expect, but this escape still surprised and challenged us.
Peter was amazingly helpful selecting Buggsy's Nightmare for us based on what we told him about the other escape we had done.
It's hard to review an escape room without giving away spoilers, but if you want a great time that you will be talking about for a while, go to Xtreme Escape.
This is perfect for a wide range of ages. We were a group of 6, ages 28-90 (our 90 y/o is pretty active), but I'd say teenagers would enjoy this as well. Not sure what the age range is, but maybe even preteens could participate. Every different perspective you can bring to the table helps in solving clues.
Trust me, you WILL NOT regret going to Xtreme Escape!
