Staterooms were clean but very small in comparison to other ships we've been on. Noise from decks above should not be heard in rooms below in a modern ship. If you book on deck 5, bring your sleeping pills as it will be noisy.
Photography is a big miss on NCL's part. Photos taken at dinner are strong-arm sold on the spot and are not available once you leave the restaurant. There are plenty of gimmicky backgrounds for pictures and no shortage of NCL badged borders. If I wanted this style of photo, I would have booked with Disney. Needless to say we did not get photos. Royal Carribbean does a much better job with photos.
Dining was generally okay but waiters hovered over us while expecting additional tip to be offered on the bill. signing with a tablet is fine but the interface is not ready for the consumer. It had very small font and looks like it was made for the employees. We had this issue at Cagneys.
Cabins on this deck are under what sounded like a roller-skating rink. Sounds of rolling carts and plumbing noises from above made this room less than ideal.
