Plot
Rusty Griswold is now working as a pilot for the low budget regional airline Econo-Air, living in suburban Chicago and in a stale relationship with his wife Debbie and their two sons, shy and awkward 14-year-old James, and naughty and sadistic 12-year-old Kevin, who constantly bullies and torments James. The gloating from his friends Jack and Nancy Peterson about a family trip they had in Paris does not help matters.
Desiring to relive his childhood family vacations and holiday gatherings, Rusty surprises his family with an alternative summer vacation. Rather than their annual trip to a cabin in Cheboygan, Michigan (which everyone else secretly hated and called Cheboring), he plans a road trip from Chicago to Walley World, just like he did with his parents and sister. For the trip, Rusty rents a Tartan Prancer, an ugly, over-complicated minivan built in Albania.
