My husband and I flew from San Diego to Buenos Aires via Dallas/Ft. Worth arriving the morning of the cruise. We sailed on Infinity February 15 from Buenos Aires. We did not have much of a chance to see Buenos Aires other than from the bus ride to the pier (we were met at the AP by Celebrity staff). Many of our fellow passengers flew in 2-3 days prior to the cruise so they had time to adapt to the time change and see the city--highly recommend advance stay. The itinerary was excellent and we enjoyed each of the ports especially Ushuaia, Argentina and Punta Arenas, Chile. One of the highlights was sailing completely around Cape Horn (it's an island). When we arrived at the Cape, the water was very calm. Living on the island is a Chilean Army Sergeant, his wife and two children. As we completed the circuit of the island, the weather (rain and wind) moved in and the ocean got a little rough. A must see is the Penguins either at Puerto Madryn or Punta Arenas. At Punta Arenas, the Penguins are the burrowing kind and their habitat is located on private property. I have a mild mobility problem so I found it very tiring to trudge out the 1 1/2 miles to the beach where the Penguins spend the day. They will rent you a battery operated cart for $25 but both carts were in use when we arrived. We understood that the walk to the Penguins in Puerto Madryn was on rough gravel whereas the one we visited was a dirt path for the first 1/2 mile followed by a boardwalk the remaining distance. Still rough walking. We did not take advantage of the ship's tours (too expensive). We went on the Penguin tour with 11 other people from the ship for a total of $22 for four hours.
The ship is very nice, always clean. The food was not up to Celebrity standards and we found most of the meats tough. We ate a lot of fish. The main seating had a lot of empty tables as there were a lot of South Americans, Germans, and other Europeans who liked to dine late so second seating was filled to capacity. We enjoyed our waiters and also Diego the wine steward from Buenos Aires (cute!).
One has to be very tolerant when sailing to this part of the world. Residents in each of the ports were very friendly and helpful. However, there were certain groups (no country identification will be made) on the ship who were very inconsiderate of others and made a practice of butting into lines and offered no excuses for their behavior. It is their culture. As someone who is mobility challenged, I found it frustrating to be repeatedly cut off by someone who acted as if they never saw me.
We ended our cruise in Valparaiso and were bused to the Santiago, Chile airport. Highly recommend taking one of the ship's tours so that you do not have to spend the whole day at the airport. Many folks enjoyed the local winery tour. Overall, we would highly recommend this cruise. It was truly a learning experience.
