We chose this cruise because of the destination. I also had fond memories of her sister ship Millennium.
It was the last trip to Antarctica (next year it will be a Solstice class ship).
We were very lucky with the weather. The previous cruise in January was not so lucky but we had calm seas for the most part with really only one day that was a bit rough. Cape Horn was dead flat, when there was fog it magically cleared as we arrived and at Elephant Island drifted back as we left. It was simply good luck and I felt sorry reading the reviews of the previous cruise.
We chose this as midships because I was thinking about rough weather and the ship pitching. It was nice cabin but the roof overhang above limited the vista. We moved to 1142 at the stern and this was larger deck and much more open. For rough water I'd stay midships but calm like the med i'd go to the rear. The rear ones were added recently so are newer also
