I would absolutely go on a cruise with NCL again. It was an amazing experience and I loved it. We were aboard the Norwegian Jewel, which was spectacular. Here are my observationa:
Public Rooms - None of them are subtle - think Las Vegas glitz. The Tzar's Palace dining room is a perfect example - lots of gilt, highly patterned, bright carpets and a grand staircase.
Cabins - All are furnished with cherry wood finishing, televisions, a safe,refrigerators, duvets, and bathrooms with showers and hair dryers. They are stylish and comfortable.
Small but ample room for the two of us, really comfortable beds and bedding. Very clean and quiet.
