The company also stated that all voyages aboard the Sea Spirit are operated with around 100 guests, "which allows for an intimate experience without overcrowding or dividing passengers for off-board excursions. The ship also features two lecture lounges, a dining room accommodating all passengers in one seating, a well-stocked polar library, and a spacious outdoor deck. Optional kayaking cruises can be booked in both polar regions, extending the reach of passengers into their frozen ecosystems. Overnight camping can also be arranged upon request for a more immersive experience on the Antarctic Peninsula. The ship's crew-to-passenger ratio of 1:9 is one of the most generous in the business."
