I actually really enjoyed this movie?
I'm not a huge fan of the raunchy comedies. The Hangover franchise, most of Sandler's films, most of Apatow's films, McFarlane's films...I just do not find funny. The original Chevy Chase vacation movies are great, but this one had me roaring. I haven't laughed so hard at a movie in a long time, maybe ever.
The plot was bare minimum, the family just traveled from one joke set to another. There were a lot of references to the old films that were snuck in. I'm glad they abruptly ended the hot girl driving the convertible joke. That was one reference that would've grown tired quick (imo).
Cameos, references, and raunchy jokes carried this movie. Setups were sloppy at times. Probably my favorite joke was the whitewater rafting with Charlie Day, and that had one of the worst setups in the entire movie. Chris Hemsworth feeding the cow ribs was funny, but then they overdid it with several more cow-eat-cow jokes.
Probably the most unfunny joke in the whole movie was Chevy Chase's attempt at physical comedy maneuvering the guitar out of the cabinet. Probably ad-libbed, and pretty dumb. He followed that up with the hilarious Bob Dillon and Jimmy Hendricks lines though.
This movie is not liked by many, and I'll probably watch it again sometime just to see if I was wrong on the first watch.

Candy is dandy, but liquor is quicker.
