We did a Seabourn cruise to Antarctica in 2020 and it was the trip of a lifetime.
Fantastic expedition team with naturalists, marine biologists, etc onboard to answer all our questions. If we were out on deck, one of the team would approach us and explain what we were looking at and answer any questions we had. Zodiac tours and landings each day while we were in Antarctica.
Every evening before dinner, we went to the theater for a de-briefing and an explanation of what to expect for tomorrow. When we walked into the theater, the expedition team lined the entry way to greet us, along with the staff offering wine, champagne, spirits and mulled wine.
If you can stretch your budget a bit beyond an O fare, don't do a sail-by. Walk among the stinky, curious penguins and have the full Antarctica experience.
ps the day in the Falklands was amazing as well!
