Las Vegas, Nev.

After making a brief stop to race dune buggies, the family checks into a massive Las Vegas suite overlooking the strip, then heads out to do some gambling and press their luck at the tables. Doug devises a plan to get a bachelor party in Vegas out of the trip. At a room service dinner in their suite, he proposes a vow renewal ceremony. Wendy is excited by the sudden romantic overtures by her husband although she's not too happy when the guys break off for a bachelor party. So she makes a deal. He can have a bachelor party if the guys agree to train for a male dancer review. The bachelor party gets botched with a bad strip club, an intercepted phone call by Wendy and a midget stripper showing up at Doug's room. The next day, for Wendy's half of the bachelorette party, she makes the guys join them for an American Thunder boot camp. After all the shenanigans are over, Wendy and Doug say "I Do" in full Elvis gear. Since the first five years were so rocky, they decide to jump into the next five years in style by going indoor skydiving.
