If I could, I'd give it no stars. This is a review of the VENUE and is in no way a review of the RHCP performance on New Year's Eve 2013. \nThis is not a concert venue. This is 3, maybe 4 conference rooms / wedding reception halls combined to make one giant space. If you are not in the first 5 rows you will not see anything but the backs of everyone's head. The Cosmopolitan billed this concert as a \""dynamic concert that will change your views on luxury, live performances and the way you celebrate New Year's Eve\"". Luxury? There were so many fights that people were bleeding right next to me. Where is the luxury in that? I had very little view of the live performance. And I have never celebrated or wish to celebrate an NYE like that again. I have felt more safe on the strip than in this over crowded room.  I have lived here for 11 years and I rarely miss a performance from any band I love. I've seen shows in almost every venue and this doesn't even qualify as a venue. An indie band can totally get away performing in this room, but an epic band like RHCP on an epic night like NYE, deserves so much more. I wasn't impressed.
