Here is the official description of the Antarctica/Patagonia Expedition Cruises:
Prepare for the adventure of a lifetime as you explore the infinite riches and natural beauty of the Antarctic Peninsula. Nature takes center stage and unique experiences abound as you hike through penguin colonies, search for pods of whales navigating the waters around you, and share a toast with fellow Adventurers as you glide past glaciers and ice floes. Plus, you’ll kick off your journey to the Antarctic Peninsula with explorations of the diverse landscapes and rich culture of Patagonia, also known as the “End of the World.”
Guests can also book an additional four-day/three-night Buenos Aires Escape, which allows even more time and experiences in the city, prior to their cruise. This Escape departs on February 18, 2022.
