Home Alone 4: Taking Back the House

Peter McCallister, who is finalizing a divorce from his wife, Kate, announces to their children, Buzz, Megan and Kevin that he and his wealthy girlfriend, Natalie Kalban, are hosting the visit of a royal family at her mansion, and invites them to spend Christmas there. After the three initially refuse, Kevin accepts the offer after being bullied by Buzz (who was supposed to be at the movies with his friends), and revels in the mansion's luxuries.
