As the smallest and oldest ship in Norwegian Cruise Line's fleet, the 2,032-passenger Norwegian Spirit is in a class by itself, literally – it's the only ship in the Spirit class. Although it was built in 1998, Spirit underwent a massive $100 million refurbishment and a recent refresh that gave it the gloss of a brand-new ship. Technical parts were updated in 2017 and a bow-to-stern interior transformation in 2020 has made it a haven for cruisers seeking a grown-up onboard ambiance. While Norwegian Spirit doesn't have the amusement park-style attractions of the line's newer vessels, its modernized staterooms, redesigned bars and lounges, fresh dining concepts, and expanded Mandara Spa deliver a solid mid-to-large-size ship experience without the megaship crowds.
