Utter crap.A halfway decent franchise gets butchered as the Griswold family hits Vegas with kids that never age, but apparently change into different people.
Clark gambles the money away. The kids do their own thing. Ellen gets swept off her feet. Blah blah blah.
Painfully unfunny. Chevy Chase can be hit (Fletch) or miss (Man Of The House). He misses here. And since it's Vegas, we get the obligatory Wayne Newton cameo. Oh, if only Wayne could act as the smooth guy trying to take Ellen (Beverly D'Angelo) away from Clark (Chase). He can't. 'Cause he's Wayne Newton. Randy Quaid has worn out his welcome as Cousin Eddie, a one-note character if ever there was one.Another fine Warner Brothers product.
