I actually would like to give them 0 out of 5 stars, but since that's not an option....
I was bored from the get-go. I was in Vegas with three guys - I wanted to do a Cirque show, they wanted to do a burlesque show. Since I'm not uptight and don't mind watching boobies, I said okay. It was actually really hard for me to not get up and walk out and I was really hoping something awesome would happen at some point, but it never did. When we walked out, all three guys told me they were sorry!
The only positive to this came from leaving and running into the open faced poker tables (Fridays and Saturdays) on the way out. Next time I'm in Vegas I'll return to The Riviera for those tables.
