The Norwegian Sun receives mixed reviews, with many guests praising the friendly and hardworking staff, enjoyable itineraries, and the value of freestyle cruising. However, there are consistent criticisms regarding the quality and variety of food, the age and cleanliness of the ship, crowded public areas, and inconsistent entertainment. Excursions are often described as overpriced or poorly organized. While some guests had an excellent experience and would cruise again, others were disappointed and would not recommend the ship. Overall, the Norwegian Sun offers a good value for budget-conscious travelers who prioritize itinerary and service over luxury and amenities.
