So on to other things. Compared to 2 years ago I think they cut down on things. Less staff that goes around the deck to sell drinks. During dinner it was even hard to get the waiter that serves wine. The cruise directer was barely doing any entertainment by the pool during sea days. (this is fine with me because I don't need it but if you're used to this on other cruise lines you will be disappointed) The sun is small so few lounges for entertainment at night so just be aware of this. the "free" dining rooms had no "wow" factor at all decoration wise and the atrium is very small at this ship.It's a well maintained ship and clean just without the "wow" factor.
For the rest the food is average cruise food. Our cabin was nice and clean. The staff super friendly everywhere on the ship.
So if all you look for is to relax and don't need awesome entertainment The Norwegian Sun is an ok ship. If you want to be "wowed" don;t choose the Sun.
