The Cosmopolitan of Las Vegas, the highly anticipated luxury resort at the heart of the Las Vegas Strip, officially opened its doors to the public at 8 p.m. on December 15. The evening's festivities included a first-look party for invited guests which included an exclusive three-song set from The Killers front-man and Las Vegas native Brandon Flowers, a dining taste-around at the P3 Commons restaurant neighborhood and a peek at the resort’s retail boutique collection. Just before the doors opened, the traditional ceremonial first bet was made by musician Mayer Hawthorne. In a first-ever innovation for the legendary Las Vegas entertainment scene, the opening-night concert was simulcast on The Cosmopolitan's marquee, meaning passersby on the Las Vegas Strip were be able to watch the concert live on the 65-foot-tall LED-display marquee.
