Unfortunately we were 30 minutes into the show before we got up, walked out and asked for a refund. The problem was not the show itself, it was the hotel (HARRAH'S hotel and Casino Las Vegas) showroom and clientele. We were seated in the theatre seats forward and there was a group of 4 grown adults seated behind us in a booth yelling, screaming, singing and basically being a nuisance the minute the show started. People in the audience were turning around trying too see who these loud mouths and making comments. They were a total distraction to the show. I did see an usher asking them to keep it down but this group seemed to act as if they owned the place. Soon enough the people in the booth next to them had enough and they start arguing face to face. Almost a full out brawl. I walked up to an usher and asked if they were going to escort these guys out? The usher then got snippy with me and said what i would like him to do? We told the usher that 90% of the audience was very angry and they should have done something 20 minutes ago. Security finally showed up but at this point we were already out at the box office getting a refund. Harrah's protocol for security in the theatre is extremely poor. We paid $100.00 per ticket for this? If you're wanting to see Million Dollar Quartet see it somewhere else. They should not be performing in this theatre. It's horrible. Harrah's no thank you.
