The Norwegian Epic receives mixed reviews, with many guests praising the staff, service, and itineraries, but expressing disappointment with the ship's design, crowded spaces, cabin layouts, and food quality. While some found the entertainment and excursions enjoyable, others felt the ship was too large and impersonal, with long lines and additional charges for many amenities. The overall experience is positive for those who value service and destinations, but the ship's size and layout, as well as inconsistent food and entertainment, detract from the experience for some travelers.
