Hey $20,000 is a big amount. i would suggest a trip from nationalgeographic's travel package which costs $10,000 , its a 14 day trip.
Like others here I have looked at many options - the south america departures dont interest me as its the history of Mawson and the Ross Ice Shelf side of things that interest me and also spending as much time as possible on the continent. I had found a price of 17K for a 23 day itinery ex hobart but hadnt considered the National Geographic options..ironic as I once worked for them!
May look into that thanks!
wow what an amazing trip it sounds;-) great discussion with loads of helpful tips. One day we want to go there as well ;-) Thanks everybody ;-)
