This is an expedition cruise ship that focusses on nature and culture. There are four tenders and 14 zodiacs for landings. Naturalists accompany passengers on shore trips and recap upon their return. There often are wet landings and climbing in and out of zodiacs in remote areas, inappropriate for people who are not physically fit. Antarctic trips that traverse the Drake Channel often encounter a stretch of quite rough water.
Past passengers receive additional discounts.
A third person is half price. Most shore excursions are complimentary. There is no tipping.
