* CrowningMomentOfHeartwarming: After being typically antagonistic as a brothers and sisters are, when Audrey freaks out about Aunt Edna's death, Rusty comforts her without a second thought.
* EarWorm: Lindsey Buckingham's "Holiday Road", which serves as the movie's theme song.
** Also the "Pig In A Poke" theme song from ''European Vacation''.
* FunnyAneurysmMoment: In ''European Vacation'', Audrey appeared in an ImagineSpot where she ate all kinds of desserts until she was full, BalloonBelly and all. This was PlayedForLaughs. In RealLife, actress Dana Hill (who had been a diabetic since her early teens) died at age 32 of a stroke brought on by her condition.
* HarsherInHindsight: The "they don't close Florida" line might qualify in light of the recent immigration incidents.
* IncestYayShipping: Dana Barron and Anthony Michael Hall as Audrey and Russ seem closer than a normal set of siblings would be, which led to speculation they had a offscreen relationship.
* NauseaFuel: The family at one point stop off at a picnic area to have some lunch. As they're eating the sandwiches they notice they're soggy, And then it hit them that Aunt Edna's dog urinated on the food. The family is understandably disgusted but Edna just shrugs and continues eating. Ugh.
* MostAnnoyingSound: Pig in a fuckin' poke.
* {{Sequelitis}}: With a different director, no creative input from Harold Ramis or Chevy Chase, completely different characterization for Russ & Audrey, and some of the better gags being telegraphed too far in advance, ''European Vacation'' is nowhere near as beloved as its predecessor or its follow-up ''Christmas Vacation''.
** The 2015 sequel/reboot is getting this reaction too with people who dislike the heavier amounts of crude humor in comparison to the original, and how the film is essentially just a kinda-sorta remake of the original (with one of the film's own trailers lampshading this fact); highlighted further by the fact the 2015 movie recreates almost shot for shot the famous "flirting with a hot woman who gets hit by a truck" scene.
* ValuesDissonance: The whole sequence in the black neighborhood was pushing things even at the time, and comes off as horrendously racist now (though it's actually ''toned down'' from the equivalent scene in the original short story).
* WhatAnIdiot: The whole mess of a vacation would have been avoided had Clark (or even the far more rational Ellen) made a simple phone call to Wally World to confirm it was open for the season; they would have learned it was "closed for repairs." (Then again, phone call equals no movie and no fun for us, the viewer.)
** Unless whatever happened to make Wally World need the repairs took place after the Griswolds departed or Clark decided to drive them somewhere else.
