Quark Expeditions added this itinerary for 2018, not sure about 2019. National Geographic has this itinerary in March and October 2019. It is more costly than my Poseidon Expeditions trip. I suspect that many travelers like to bundle a just few days in South Georgia and the Falklands with Antarctica. If there is bad weather in this area, you could miss the opportunity for zodiac landings and/or zodiac cruising and sail past South Georgia and the Falklands. With a dedicated itinerary, you are more likely to make several landings in this area. That said, there are never any guarantees as weather can turn quickly. Safety is always a priority.
