Courtesy Virgin Hotels Pandemic casino boom in Vegas Any discussion of the latest and greatest in Las Vegas must start with the city's newest casino resorts. The latest entry, Virgin Hotels Las Vegas, opened March 25 in a reconceptualized version of the off-Strip space formerly occupied by the Hard Rock Casino Hotel. This property has more than 1,500 rooms, a 60,000-square-foot casino, a 4,500-seat concert hall and an expansive pool area with a resort pool, a Mykonos-themed day club and an event lawn. While the resort retained Nobu and some of the same restaurants as its predecessor, it also added a lineup of new ones, including One Steakhouse from brothers David and Michael Morton.
