Norwegian should be up front with its passengers that the Sun is their training ship and the cruise fare should reflect the reduction in quality of service.
If you have been on any cruise line before, you are used to a professional and pleasant crew. With a Sun crew of 800+, at least 100 are in training - and it shows. There were missteps throughout the entire cruise: towels not delivered, wrong dinner menus on the tables, knives served with dessert instead of spoons, dirty public bathrooms, pools closed for training, passengers evicted from deck seating which was closed at 9:30 am for a crew party (figure that one out!), crew huddled in corners talking while tables waited to be cleaned, female servers slapping the rear ends of male servers, sour faced rude unsmiling servers. Of course, there were a handful of wonderful experienced crew that went out of their way to make up for the rookie mistakes, but it wasn’t enough to make me sail this ship again.
The Sun is in serious need of renovation. Outside cabin 4208 had a stained bed skirt, lumpy mattress, couch that opened up on its own every time you sat down, and a bathroom counter that needed caulking. Bathroom linens were stained, sometimes so bad that I wouldn’t use them. Leather couches in the Java café were torn.
On the positive side, the itinerary was wonderful and the food, while sparse, was good. Still, I’d suggest you find another ship.
