M13, T12: The eight remaining contestants head to the tropical paradise of Hawaii for an action-packed week that will address the excuse "I can’t lose weight on vacation." After being warmly welcomed to Oahu with a luau, the players compete in a trivia challenge that awards the winner a cash prize which can be spent on a menu of items. Next it’s off to the breathtaking Kualoa Ranch where "Jurassic Park" was filmed and there the contestants race through a challenge involving tikis and leis for the coveted prize of immunity. Later, a young woman who epitomizes "no excuses" - real-life "Soul Surfer" Bethany Hamilton - teaches the contestants and trainers how to surf. Then at Pearl Harbor, with the USS Missouri in the background, the contestants weigh in to reveal whether they were able to lose weight on vacation before another player is sent home. Alison Sweeney hosts the series and trainers Bob Harper and Dolvett Quince also star.
