The last sentence of this on-line review of the movie would seem to have the answer:

Co-scripted by John Hughes, then maestro of the teen pic, this politically incorrect
comedy from director Amy Heckerling should be dismissed without hesitation. But there
is something endearing about the Griswold family, and Chevy Chase and Beverly
D'Angelo's infectious enthusiasm manages to sweep you along (as begrudgingly as kids
Jason Lively and Dana Hill) on this cliché-ridden package tour. Every conceivable national
stereotype is pressed into service, as polite British cyclists, rude French waiters,
aggressive Germans in lederhosen and Mafia hit men are trotted out with soothing
predictability. Nothing could prepare you for the highlight, however a whistle-stop tour of
the Louvre to legendary Belgian pop star Plastic Bertrand's seminal song Ça Plâne pour
Moi.
