We chose the ship because of the itinerary and our previous positive experience with Norwegian. We especially like the free style dining. The service on the ship was generally outstanding. People were friendly and genuinely helpful. This was especially true of the restaurant staff. They did a great job of serving meals. We like the specialty restaurants so had a 9 night package out of the 15 nights for the cruise. They were all excellent. The two non-specialty restaurants were also good, although their menus got a little boring after a while. I really don't like buffets so we only ate there when we had to. The food was ok, but it was annoying to stand in line and look for a table, etc. You could easily avoid the buffets with other choices.
Embarkation was ok. It took a while to get through the process. The first Norwegian cruise we went on we got there right when they opened and had to hang out for a few hours to be able to get into our cabin. This time we arrived about 2 pm for a 5 pm deadline and it worked better. Disembarkation was ok. The problem wasn't with Norwegian, but with Buenos Aires. Their process resulted in long lines. Once you got through the process the taxi line had at least 100 people in it. It took us 30-45 minutes to get a taxi and it cost 400 pesos (about $24) for a 1.5 mile trip. We later paid about 100 pesos on the meter for the same distance.
The service was great. Our cabin attendant wasn't as good as others on the ship, judging from their experience, but she was adequate. The restaurant service was excellent. Since we spent a lot of time in the Specialty Restaurants we got to know some of them quite well. Grace, the Maitre De was very friendly and was excellent. The food in all of the areas was good to excellent.
The cabin was nicely appointed with a log of storage and plenty of room to put suitcases under the bed. It was small but nice. The window was large and let in a lot of light. It allowed the bed to be up against the outside wall which gave you more room in the cabin. The location was convenient. There were a couple of disadvantages. The two main restaurants are on 5 so you can't walk through which meant that you had to go up and down stairs to go around the blockage. Our room was right under the walking/jogging track. We heard very little noise and they blocked off the area from 8 pm to 8 am which helped a lot.
