Poseidon Expeditions
All-suite expedition cruising aboard the 114-passenger Sea Spirit
Poseidon Expeditions consistently earns top marks for its South Georgia itineraries — and for good reason. Their 114-passenger Sea Spirit is the only all-suite ship in its class operating to South Georgia, meaning every guest enjoys private suite accommodation without paying ultra-luxury pricing. With all 114 guests able to go ashore near-simultaneously (IAATO permits this at some sites), the ship avoids the frustrating rotation delays that longer vessels impose. The expedition team — naturalists, marine biologists, geologists, and historians — has been consistently rated among the finest by repeat polar travellers. Poseidon has been an IAATO member since 2011 and was named Best Polar Expedition Cruise Operator by the International Travel Awards from 2022 to 2025.
