No one will be eliminated, but the 27th season of MTV's venerable reality series drops seven strangers -- castaways, "Survivor"-style -- on the busy harbor of St. Thomas in the U.S. Virgin Islands. The cast -- four guys and three gals -- include a homeless "Southie" from Boston, a sassy Virginia State University graduate, a star athlete from Baltimore, and a party lover from Staten Island, N.Y., who is always looking for Mr. Right, or at least Mr. Right Now. The roommates gleefully immerse themselves in a Caribbean lifestyle, partaking in the traditional Carnival parade and countless water activities, while absorbing as much rum and sun as possible.
