Nobody plans a vacation better than Clark Griswold. This time out, Clark has finally chosen the perfect destination. He's selected the Promised Land where the Griswolds can enjoy their own special brand of kinship and reach certain vacation nirvana: the new family-entertainment capital of America -- Las Vegas, Nevada. But Clark didn't count on one thing. Despite Vegas' new image as a city with wholesome activities for the whole family to enjoy, its tempting underbelly still lures the unsuspecting with its glitzy, glammy enchantments. And each wide-eyed member of the Griswold gang becomes seduced by the easy enticements of Sin City. Can the Griswolds come back together once they've tasted the high life in Lost Wages? Before their Vegas voyage is over, they'll see and do it all: wonder at the illusion of a Siegfried & Roy stage extravaganza, scale the dizzying heights of the Hoover Dam, thrill at the bulbs and buzz on the Strip and indulge in the decadent pleasures of the big-ticket suites.
