Norwegian's well-designed, mid-sized ships sail under the “Freestyle Cruising” concept, which offers a more relaxed, resort-style cruise with greater flexibility and high standard, non-intrusive service. NCL has more than 100 cruise itineraries, ranging from three to 23 days across the globe. Its ships appeals to those seeking a good value on a midrange cruise. A service charge of $12 per person, per day will be added to your onboard account. This is a fixed service charge and is not adjustable unless, in the unlikely event that Norwegian Cruise Lines cannot satisfactorily resolve the issue through their guest satisfaction program, guests will be able to adjust the service charge according to the level of inconvenience they feel they have experienced.*A 15% gratuity is added for bar drinks and 18% for spa services.
