The Duncans are separated on route to Amy’s (Leigh-Allyn Baker) parents in Palm Springs after Teddy (Bridgit Mendler) makes a snap decision to give up her airline seat for a free ticket. Unwilling to let her daughter travel alone, Amy also disembarks the plane only to discover the next flight to Palm Springs departs after Christmas, on December 26. Meanwhile, the rest of the family arrives in Palm Springs, but things aren’t any easier as Bob (Eric Allan Kramer) tries to care for Charlie (Mia Talerico) under the watchful eye of Amy’s mom Petunia (Debra Monk) who does not like Bob at all; PJ (Jason Dolley) learns the pros and cons of his grandparents’ pool after getting a sunburn, and Gabe (Bradley Steven Perry) quickly realizes the downfalls of teaching Grandpa Hank (Michael Kagan) how to play his video game and Grandpa becomes addicted. Meanwhile, Teddy finds out Amy is pregnant. They get into an argument when they later make up, they sing to get some money for food, as somebody has stolen their luggage. They find the girl who has stolen it and she apologizes for stealing their stuff. Teddy gives her the free plane ticket so she can get home for Christmas. The boys (PJ, Bob, and Gabe) go to Las Vegas and save them and they finally get the Christmas vacation they wanted. At the very end of the film, the grandparents show up with Charlie, and Amy reveals to the family she is having another baby.
