With room for 4,000 or more passengers, the biggest Norwegian Cruise Line ships are among the most massive resorts you'll find at sea from any cruise line and are comparable to some of the biggest resorts on land, too. They have the biggest spas and casinos among vessels in the Norwegian fleet and the most cabins and suites - as well as the most variation in suite and cabin types. The biggest Norwegian Cruise Line ships are, almost by definition, the Norwegian Cruise Line ships with the most 'stuff' - the most pools, waterslides and other deck-top attractions ( even go-kart tracks), as well as the most onboard restaurants, bars and showrooms. Are you looking for the most megaresort-like, activity-packed Norwegian Cruise Line ships at sea? If so, you'll want to get on one of the biggest Norwegian Cruise Line ships.
