Not this year. But one day I will.
You probably already know, but look at cruises out of Ushuaia, Argentina.
And once you've checked Antarctic off your list, one day you'll have to fly to Madagascar, and board a French "cruise", I put cruise in quotes because it's actually a French cargo vessel that unofficially allows civilian passengers on for a pirce-- that departs Madagascar, sails for two weeks 2000 miles deep into the remote and unforgiving southern Indian Ocean to reach the most remote, untouched, and fascinating islands on the planet-- Kerguelen.
