Lloyd's mom and Francine are going to Zizmo Beach which Lloyd thinks is babyish and even worse they are going to McZorks' afterwards. Lloyd declines to spend a weekend with the McNoggins but they are too boring. Then he spends a weekend with the Blobberts but they are too babyish. He then goes to Eddie's family but they are too boring as well. He starts to miss his family and he'd do anything to see them again even if it means going to Zizmo Beach.
