You know, this movie and the Vacation remake made me realize that no one takes holidays like this anymore.  Remember, this was when that awful word "stay-cation" was being bandied about because people couldn't afford to go out and do sh*t.  So really, what we needed was a remake of The Burbs.  Millers is very much making fun of the idea of a family trip, there's nothing in there that's inspired by actual events or memories like the original Vacation was.
