It seems like just yesterday when we were talking about how nothing major was going on in Las Vegas. How quickly things change. MGM Mirage announced this morning it is selling Treasure Island to former New Frontier owner Phil Ruffin. What does this mean for TI? Will Sirens’ Cove be filled with mud for the return of Cold Beer, Dirty Girls? Will Christian Audigier: The Nightclub be replaced by Gilley’s? Will Sigma Derby return to the north end of The Strip? Will Ruffin resurrect his plans for either City by the Bay or Montreux? We’ll ponder these and other questions about Treasure Island on the next show.

Five Hundy by Midnight has learned The Second City Las Vegas is closing its doors on Aug. 1. The Las Vegas branch of the legendary improvisational comedy theater has occupied the small showroom at Flamingo since 2001. Considering the revolving door of mid-priced shows on The Strip in that time, a seven-year run is pretty impressive. No word yet regarding what Flamingo has planned for the showroom nor whether The Second City is seeking a new Las Vegas home. An official announcement about the closing is expected later this week.

MGM Mirage today confirmed ARIA is the name of the resort and casino at CityCenter.

Harrah’s Entertainment, the ginormous casino owner we love to hate and hate to love, announced today it is changing its name to Caesars Entertainment. This isn’t a huge surprise, as the Caesars name carries more prestige.

In 2004, Park Place Entertainment, then-owner of Flamingo, Bally’s, Paris and Caesars Palace along with a bunch of casinos outside of Las Vegas, changed its name to Caesars Entertainment. Harrah’s Entertainment acquired Caesars Entertainment a few months later.

So what does this name change mean? When we complain about diminishing diamond lounge benefits and 10 minutes later rave about free room offers, we’ll be calling it Caesars instead of Harrah’s. Other than that, probably not much.

If your heart (or other part of your anatomy) is set on staying at Hooters Casino Hotel, now is the time. New owners plan to dump the Hooters theme.
