I liked that there were many countries/cities to experience and understood that there wouldn't be enough time to see them in-depth.
The pre-arranged bus from my hotel in Copenhagen to the ship made the trip stress free. It was easy to check in and luggage was delivered promptly. (On other cruises I had to wait hours.) The pub was available for lunch and both the food and service was good. I never went to the buffet -- too noisy, germ filled and crowded, so I was glad that there was a O'Sheeran's, a great alternative.
I had a balcony stateroom that was assigned by Norwegian. Except for the narrow space between the side of the king sized bed and the closet doors, the room was good. It never occurred to me that my balcony was a waste when the weather is cold, rainy, and/or cloudy the entire cruise and it gets dark early and daylight begins later. Also, select your cabin carefully as my cabin was forward. It is such a large ship that it took a lot of steps and time to get to the elevators.
