Rusty Griswold, the youngest child from 1983's National Lampoon's Vacation is all grown up with a family of his own and fond childhood memories of a certain family road trip to Walley World, "America's Favorite Family Fun Park." Like his father, Clark (Chevy Chase), Rusty wants to forge closer bonds with his own family - wife Debbie (Christina Applegate) and boys James and Kevin (Skyler Gisondo and Steele Stebbins) - so he buys a souped-up Albanian van and convinces them to set off on their own crazy cross-country jaunt to Walley World. Directed by John Francis Daley and Jonathan M. Goldstein.
