We traveled back-to-back cruises, Antarctica and the Chilean fjords, on the Silver Explorer in February/March 2012. The brilliant expedition team; marine biologist, geologists, ornithologist, botanist, historian were available to answer questions almost 24/7. They doubled as our zodiac drivers, accompanying us on all landings and excursions. Lectures every sea day from these professionals added enormously to our understanding and enjoyment.
Silver Explorer has an open bridge, officers and crew happy to explain what's happening.
Zodiac expeditions were well organised, generally two a day while in Antarctica. Because only 100 pasengers are allowed to land at one time, 60 would land while others did a zodiac cruise. We had plenty of time onshore, the area you can explore is limited, usually by inaccessible cliffs of ice and some environmentally sensitive area declared out of bounds.
Spacious cabin, large window, good sized bathroom with bath and shower over bath. Plenty of closet space. Mid-ships on lower deck so very stable in rough seas. No noise from hallway or other cabins.
