This was our 3rd cruise overall and first on NCL. Overall it was a good experience and we'd consider a repeat cruise if the ports of call were different.
We booked one of the two Owner's Suites, Cabin 9708. The cabin was very well laid out, large, and pretty to look at. The small dining area was perfect for breakfast setup and other room service meals. The main sitting are easily accommodates 4 and has a 21 inch TV. Bedroom also has a (smaller) TV. The bed was super-comfy and sheets were very high quality.
Bathroom was large, with a double-sized Jacuzzi and 2 picture windows so you can gaze out over the ship's wake as you soak. There is a separate shower with good water pressure and flow. Complementary toiletries were provided. There is a separate guest bathroom which is also roomy and nice.
