Clark Griswold is on a quest to take his family to the Walley World theme park for a vacation, but things don't go exactly as planned.

The Griswolds win a vacation to Europe on a game show, and so pack their bags for the continent. They do their best to catch the flavor of Europe, but they just don't know how to be be good tourists. Besides, they have trouble taking holidays in countries where they CAN speak the language.

The Griswold family hits the road again for a typically ill-fated vacation, this time to the glitzy mecca of slots and showgirls—Las Vegas.

It's Christmastime, and the Griswolds are preparing for a family seasonal celebration. But things never run smoothly for Clark, his wife Ellen, and their two kids. Clark's continual bad luck is worsened by his obnoxious family guests, but he manages to keep going, knowing that his Christmas bonus is due soon.
