Excellent itinerary on the NCL Sun. Small ship for 14 days, but the itinerary is awesome. We did two days in Buenos Aires before the cruise (must do the hop on hop off bus) and then did two days in Santiago after the cruise. This is a long vacation but do worth it. Ushuaia is awesome little town at the end of the world. Falkland Islands was fun. We did the 4x4 penguin tour which was excellent. Getting to see Cape Horn and the end of the continent. The Chilean fjords were awesome--balcony room is recommended for this cruise to see everything. The glaciers were also very nice. Pack your winter gear for that portion as it gets colder as you go south. The cruise ended in San Antonio and we had to pay $100 to get a private car to take us to our hotel in Santiago. Santiago is an interesting city with lots of recent history. Must see there is the Human Rights museum and take the funicular up to the Mary statue.
On the ship, we ate at Le Bistro --nice -- and Los Lobos and La Cucina both twice Los Lobos had good mexican good and was never crowded. On the sun there is a sauna and steam room that you don't have to pay for. That was great for a 14 day cruise. Take advantage of it. The spa locker room is small as well as the relaxation area after your sauna. The buffet was normal and got boring after a week, but there is something for everyone--the buffet had some special ethnic nights which was good.
The cabin was great and balcony was perfect for this cruise. However, we were in the back and had lots of vibration from the engines pulling into port. So we were awakened at 4am some days.
Arrived two day early and explored this beautiful city. Did the hop on hop off bus which was so worth a two day ticket. I stayed at the Recoleta Luxury Hotel which was close to everything and walking distance to Peron's tomb.
