Flamingo Las Vegas:With its brilliant pink facade, the Flamingo Las Vegas is as colorful as the history behind it. It seems appropriate that the Flamingo Las Vegas is a direct descendant of the hotel where modern Vegas began. Benjamin "Bugsy" Siegel's original Flamingo is gone, but the hotel that bears the name continues to live up to its name. The lush gardens behind the room towers seem removed from Sin City entirely, with live African penguins, Chilean flamingos, Mandarin ducks and Koi fish frolicking in ponds and under three-story waterfalls. A number of tennis courts, swimming pools and a world-class health spa make the Flamingo seem less a casino and more of a full resort.
