Ocean adventure, Antarctic from Australasia?

I have been thinking about the most unusual holiday that I could take, and the Antarctic springs to mind. I have now found a company that offers Ocean adventures, in other words, "cruises" starting from Australasia and ending up at the Antarctic. What do you think? Would this be fun?

Sure. If you are not someone who hates extreme colds (like me), have the patience to sit on a small ex icebreaker ship (unlike me) and think that a grand or ten is a reasonable amount to cough u for such trip (again unlike me) then I am sure that it will be a lot of fun.
