A few years ago we did a cruise around South America on a 'something' of the seas (lol, I can’t remember which ship). We had to take the Straights of Magellan because the seas were way too rough. Even the Straights were something else! Could not go on deck at all. We were in the Diamond Lounge in the evening and you had to wait and run to your seats with your snacks to go with the flow. Love that!
