We had a wonderful time on the Buenos Aires to Valparaiso cruise. Oceania does a great job of providing a spacious cabin, we had a verandah, delicious food, all the specialty restaurants are excellent and we had some memorable meals in the main dining room, and most shows were good. I love the barista, visited there often for excellent coffees.
We had been in Buenos Aires for 3 nights and there were no other passengers embarking at time we arrived. The biggest complaint would be the tender experiences. When you were not on an Oceania excursion it was not easy to get an early tender. Mostly it made some of our independent tour arrangements difficult. We also missed a stand by chance on an independent tour because we had to wait 1 hour and 30 minutes in the theater before our number was called. We also had a very difficult time docking at the ship one day. No warning was given and we slammed into the ship three times. It would have helped if we had known to brace. I actually was seated beneath the pilot and there is a metal post forward of the bench. I hit my shoulder and head. We also tried docking on the opposite side of the ship and again slammed into the ship three times. I know the crew was trying super hard to get us docked. It was a rather harrowing experience. Not one I would like to repeat.
All the specialty restaurants are excellent for food and service. Although I did not think we had good service in Jacques. The main dining room does have some issues with the service and the staff understanding some of our requests. We did have some excellent food and especially desserts in the main. I will say one night my steak was not the way I ordered it and after 3 tries I finally just accepted the steak they served. I do not like buffets and I did tire of using the buffet although the choices were good but service could vary. The waves is a nice option and service was always good.
Good size with a nice verandah.
