Prior to my Vegas trip I was looking for tickets to one of the Cirque shows. Everywhere was just so pricey I just gave up. Upon arriving at the strip I discovered these booths that were selling tickets 4 less! WOW!
The lines can be very long. You should get there right when they open up. Just get there before 10am so you can score some good deals. Although they do update their stock throughout the day so it can hard to tell. They not only sell tickets to shows but also discounts to restaurants.
I got my ass here around 10am and there was a very short line. I was able to get tickets to Mystere for ~$90 with fees and such already calculated. I also bought a discount for Wolfgang Puck Pizzeria & Cucina. $4 for 20% off the entire bill. Plus they make reservations for you. Nice! After I bought the Cirque tickets I had to walk all the way to Treasure Island to pick my seats. I was able to get seats in the 2nd row from the stage. AMAZING! Really great deal.
My low rating is for
-long long long lines during the day
-those hidden fees that you don't know about
-you have to go there the day of to find out what they have
-not always a great deal
