Ma guarda un po' 'sti americani

Ellen calls Clark "Sparky" in all four Vacation movies. In the DVD commentary for this movie, Chevy Chase said that the nickname was Beverly D'Angelo's idea, and she still affectionately calls him Sparky.

When the Griswalds abandon their car in Germany, they also abandoned their luggage. Yet when they are on the train, they have changed clothes.

The opening credits are stamped on various parts of passports, including the passport photos of the cast.

A recent airing on AMC has the following edits: 1) the scene with the topless female aerobic dancers is completely cut out; 2) Helga's subtitled reply when the Griswalds leave is "Beats the crap out of me"; 3) when Claudia unbuttons her top, we do not see her bare breasts, and Rusty's reaction is "Holy ****"; 4) at the last scene with Claudia when the bells are ringing, we are zoomed to see just Rusty and Claudia's heads.
