I’m sure you guys have researched this trip well as always.

Friends of ours went on something very similar with Silversea. Bucket list to visit continent and see penquins.

Hopefully you get fair winds and seas but I would be prepared for anything based on their accounts.

The high waves/highwinds they experienced on Drakes Passage were massive and they were confined to their cabins and slept with life jackets.

They had to buy/ rent all kinds of special exposure clothing/gear and were required to buy/have a massive travel insurance policy.

They did survive, they did go ashore in zodiac boats and they did love the Penguins, mega-thousands of them. Trip of a life time.
