The adopted sons of the Hayes-Brown family want to thank their loving father by nominating him for a vacation to the Caribbean. They set sail with Tommy and Andrea to the enchanted island of Grand Turk, where they power snorkel in crystal-clear water and discover treasures of the sea. Next, the family gets a fun-filled dose of island culture when they learn about the music of the Caribbean and the region's signature dance. Back on board the ship, the family caps off their voyage with a party to celebrate a high school graduation and pay tribute to their father.
