This was our 45th cruise, but only our second NCL cruise (the first was the Norway in 1984). Having cruised most frequently with Princess, we thought we would give NCL a try with this cruise on the Norwegian Star.
Overall impression and recommendation: We are not easily impressed. We would definitely sail on this ship again in a heartbeat. The ship and all of its themed public rooms are gorgeous, with a friendly and efficient crew. The food is excellent (other than the buffet on Deck 12), as is the freestyle dining option.
Your fellow cruisers: This is a much younger crowd than Princess. Especially at holiday, it's more boisterous, with lots of first-time cruisers. Many families with young children. There is a much more casual feel, but not as casual as Carnival. It was actually quite comfortable and fun.
