CNBC's "CRUISE INC: BIG MONEY ON THE HIGH SEAS," REPORTED BY PETER GREENBERG, EXAMINES THE $30 BILLION CRUISE INDUSTRY

They are 90,000-ton floating cities: self contained resorts, shopping malls, swim parks, casinos, and nightclubs, offering passengers everything from art auctions to Botox. In the $30 billion cruise business the journey is the destination, but in an increasingly punishing economy, the industry is sailing in rough waters.

In the CNBC Original, "Cruise Inc: Big Money On The High Seas" Correspondent Peter Greenberg and his crew investigate the strengths and weaknesses of the fastest growing segment of travel, as they spend seven days aboard the Norwegian Pearl, one of the newest ships in Norwegian Cruise Line's fleet. Fifteen stories tall and more than three football fields long, The Pearl is home to more than 4,000 passengers and crew, and Greenberg was granted extraordinary access above and below deck to document the inner workings of the ship and the business itself.

Greenberg investigates the intricate pricing structure of the cruise industry, starting with the most luxurious accommodations, which go for $26,000 a week, butler included. He explains the huge gap that exists between the baseline cabin fee and the actual cost of indulging all the ship has to offer. The report also explores common perceptions and misperceptions about safety and security at sea, and takes viewers behind the scenes as the crew of the Norwegian Pearl train for worst-case scenarios. CNBC gets a rare look at the Pearl's state-of-the-art security operation, where officials use 1,100 surveillance cameras to monitor the ship 24/7.
