Our cabin (standard balcony) was a great layout and very spacious. It was the best thing about the cruise.
The ship itself was really designed for a warm weather environment. Unfortunately, our cruise was in the northern latitudes (NY to Southampton) and, due to weather, most of the outside areas were closed. This lead to the ship feeling very crowded.
As far as I'm concerned, freestyle dining is dead. Once upon a time, one could show up at a NCL main dining room and get a table fairly quickly. However, since NCL started allowing reservations, everything gets booked up on day one and now just showing up often entails a 30+ minute wait. I'd rather they offer a fixed seating.
Very spacious and a nice layout. Best thing about the ship.
