Carnival and M&M’S® have teamed up once again for their annual “Frightfully Fun” promotion aboard all “Fun Ship” voyages departing between Oct. 17 and 31, 2009.

During the “Frightfully Fun” promotion, guests sailing with Carnival can enjoy a variety of fun-filled activities, everything from costume contests and Halloween-themed giveaways to scary movies, and, of course, trick or treating, with candies and other goodies from M&M’S®.

All guests sailing during the period are encouraged to bring their costumes and participate in the costume contest and parade.

Guests up to14 years of age are also invited to go trick or treating along the ship’s promenade and through various public areas to stock up on M&M’S® signature candies, including MILKY WAY®, SNICKERS®, SKITTLES®, STARBURST® and TWIX®.
