Mayhem ensues when the Griswolds go to Las Vegas in this fourth film in the 'Vacation' franchise. Chevy Chase is solid as always and Wallace Shawn has a fun extended cameo this time round as a condescending croupier, but with minimal road trip elements here, the dynamic is not quite as juicy as the first or even second film. The plot basically consists of each member of the Griswold clan having their own individual Vegas experiences, and while there is quite a bit of oddball humour in how Rusty makes it as a gambling king, there is not a lot of interest in Audrey becoming a Vegas dancer, Ellen being seduced by Wayne Netwon or Clark's gambling debt woes (Shawn's role in the matter aside). The recasting of the kids (yet again) also works against the film; while Marisol Nichols and Ethan Embry are both older than the characters they are playing, they don't look it, while Chase - with grey hair now - looks older than ever. Randy Quaid also has far too much screen time for his own good as the abrasive cousin Eddie and it is hard to know what to make of a scene in which Quaid and Chase visit an outskirts casino with "what number am I thinking of" gambling games. The solution to Chase's gambling woes comes a little too easily too. There are, however, enough scattered good moments here to make the film possibly worth a look. The return of the blonde in a convertible (from the first film) is a nice touch, some dam wordplay surprisingly works well, a sun-roof incident is quite funny and what a way the film depicts to obtain a fake ID!
