Other mistake: Most evident in the massage scene, Jilly's gold ID bracelet on his left wrist is inscribed with the name "Jerry". Jilly is played by Jerry Weintraub.
Other mistake: If you watch closely when the Griswolds approach the limo driver at the airport, you will see a pilot with glasses walk by in the background, and he sticks his tongue out at the camera and looks right at it.
Other mistake: While touring the dam, Catherine (Ellen's cousin) mentions that Eddie told her that they'll get electricity some day. But earlier, we saw a working refrigerator (with a light that went on and off) in the trailer's kitchenette. When Eddie and Clark are digging for the buried money at night, we also see lights on the trailer's exterior.
Other mistake: In this film, the oldest son of Catherine and Eddie is named Denny. In the original film, his name was Dale. He looks the same (although a different actor used) so it's under the assumption it's the same kid.
Other mistake: When Rusty put coins into the slot machine to win the first car, he only put in 2 coins, but if you look closely at the payout table, he would have had to put in 3 coins to win the car. The same thing happened when he won the Viper. Also, when he won the Viper, the light on the top of the slot machine did not flash on and off, which would have happened if he had any type of big win.
Other mistake: At the end of the movie, there is a sign that says "Chicago 1880 miles." First, it's not 1,880 miles from Las Vegas to Chicago, it's closer to 1,750 miles, but also the road they were driving on was heading west, so they would have ended up in California.
