The Concierge and the Butler were great and went out their way to help us. I highly recommend that you spend the extra to get a cabin where the concierge and butler services are offered. It is worth it.
The food was mediocre at best. We don't cruise for the food and had heard the Norwegian Sun was not known for excellence in the food category so it was not a big disappointment. However, I would have enjoyed the trip more had the food been a bit higher quality. We had several meals in the Four Seasons, but preferred the specialty restaurants particularly Pacific Heights. Il Adagio was also very good. Because of booking an AD Suite, we were able to enjoy the Concierge Lounge (Il Adagio) for breakfast and lunch. This is a very nice way to enjoy a quiet, relaxed meal during the day.
We decided to do the Behind The Scenes tour that is offered onboard (at the price of $55 per person). It was okay but not worth it. The group was too big and it was hard to hear the tour guide particularly in the kitchen prep areas. There are no microphones, and coupled with the noise in the kitchen area (which is expected) one could not hear what was being explained unless you were right in front of the guide. The rest of the tour went better, particularly seeing the bridge and meeting the captain. Again, I wouldn't repeat the tour on another cruise.
We met some very interesting people during the 14 days and we got to see a lot of very unusual and interesting sights on our shore excursions. The trip is rustic and many of the trips included rough roads. Weather ranges from very hot to very cold so bring clothes accordingly.
One big disappointment (not the fault of the ship) was we couldn't get off to go to the Falklands. The weather was so bad. The Falklands is a tender port and the day we arrived, the winds were gusting to 60 mps which made it impossible to take tenders into town. We heard that this was not uncommon. One man said he had tried twice and had never yet made it to shore. Another person said they had tried four times and never made it. Maybe NCL should consider skipping the Falklands and extending the stay at Montevideo or some other of the other ports. By the way Montevideo is great as is Buenos Aires.
Overall it was a great trip. We are glad that we went and saw parts of the world we never thought we would see. Now it's on to other parts of the world!
Happy Cruising to All!
