The person who has everything probably doesn’t have this: a voyage to Antarctica, the trip of a lifetime. Right now Poseidon Expeditions/Expedition Cruises is offering up to $2,200 off the price of a trip to the White Continent.

Their 12-day Classic Antarctica voyage, beginning December 10, 2013, is now discounted at $5,795 p.p.d.o., marked down from $7,995. They also have limited availability on the cruise beginning January 2, 2014. Book before November 30.

The Classic Antarctica voyage offers all the essential experiences of the Sixth Continent, including huge icebergs, five penguin species, six seal species, several whale species, scientific research stations representing several different countries and landings to the mainland of Antarctica.

These prices are offered for a limited time only, and only a few berths remain. Also available is the opportunity to visit the North Pole on the Russian nuclear icebreaker 50 Years of Victory in summer 2014.
