Les Chester en Floride

Karen Austin (Sandy Chester) was only 29 when the movie was filmed, and is less than 12 years older than Kerri Green, who played her daughter.

When Richard Crenna's character, Al Pellet, buys the house that John Candy's character is renting for the summer he tears up Candy's check and says "I want you and your entire family out by Saturday, Midnight, or else...". When purchasing a property with a renter who has a legal contract, the purchaser of that property is legally obligated to honor all current rental/lease contracts. In this situation Pellet's only option is to honor the summer rental contract. Otherwise, he would be subject to legal action.

Pictures of the family are shown during end credits

There are many scenes that were cut from the movie that mostly dealt with the development of John Candy's character and the family before the vacation. There is about 5 minutes snipped out of the first 15-20 min of the film. They include:

• Jack Chester pulling over to the side of the highway, telling the kids that the car is not moving until he has five seconds of silence.
• Also on the way to Citrus Cove, Florida, they get fast food. The dog farts at this time, causing the family to stick their heads out the window.
• When they arrive at the "wrong" house, they shows snips here and there through the course of their stay of Archie "the dog" chewing the leg off the couch.
• Then, after Jack Chester unloads the trailer, there is another deleted scene involving Bobby and Jennifer about who gets the color TV.
• Also, before they leave the house, Dan Gardner, "the owner" of the wrong house, they are staying at tells them that it is their house and not the Chesters', you see both of their expressions as to what they are felling at that moment when he and Jack Chester are in disagreement.
• When the family leaves to go to the right house, Jack Chester says, "Have a nice summer". Following that, the two owners that own the house laugh and the couch breaks (a result of Archie's gnawing on the couch leg) and they fall backwards.
• Finally, the scene where they arrive at the Barnacle for their dinner, there is a scene added to fill in for the edited scene where Laurie says, "This place sucks," instead of showing that they added a very brief scene of Rip Torn's character "Scully" approaching their table.
