Norwegian Sun underwent a refurbishment in spring 2018 during which it received the Mexican eatery Los Lobos (replacing Las Ramblas Bar and Restaurant), Bliss Ultra Lounge (replacing Dazzles) and the Spinnaker Lounge (replacing the Observations Lounge). Additionally, all cabins and suites were outfitted with USB charging ports.
When it debuted in late 2001, Norwegian Sun was considered Norwegian Cruise Line's first real innovator. It was the first cruise ship the line built expressly for the "Freestyle Dining" concept, and raised quite a few eyebrows when it launched with nine -- count 'em nine -- restaurants. Even its launch was unusual -- the ship shared a splashy dual premier ceremony with Norwegian Star in Miami (how many cruise lines can you remember that actually debuted two new-builds on the same exact date and at the same locale?).
What's kept Norwegian Sun up to date is continaully refurbs. In 2016, the ship received the company's latest additions, bringing the number of restaurants up to 14. The company also deploys the ship on some of its longer itineraries; South America is a mainstay. You'll rarely find families on these journeys, which makes Sun a great choice for couples who love mainstream cruising.
In fact, with so many ships and cruise lines from which to choose, it's often the little things that make a difference between a great experience and one that is so-so. For me, it's usually staff and crew behavior that drives my appreciation, and then touches like porcelain cups and real cream at the coffee stations, well-maintained and clean public rooms, attentive room stewards and enjoyable activities for all age groups. All of these factors are present on this ship.
