Norwegian Cruise Line is extending the Nickelodeon family entertainment to a third ship, the Norwegian Gem, beginning in February. Each cruise will feature a live Nickelodeon-themed show in the main theater, Nick Live Poolside! with games and activities by the pool, character breakfast with characters such as SpongeBob SquarePants and Dora’s Dance Party. Other family activities include Nick Jr. Story Time, family trivia and arts and crafts sessions.  The ship is sailing seven-day Bahamas and Florida voyages from New York City through September 1. Ports of call include Port Canaveral, Great Stirrup Cay and Nassau.  Nickelodeon-themed shows and activities were first introduced in April 2010 on Norwegian Jewel and in July 2010 on Norwegian Epic.
