The Antarctic is an incredibly unique environment - it's like nothing ever before! The Antarctic has awesome animals that people will never have seen, which I believe is a huge factor in the tourism rates.
Going to the Antarctic is an adventure to people - they want to survive in a new and special environment that will test their limits in a habitat that they aren't used to. With the extreme cold and special animals, the Antarctic is bound to be a tourist favourite.
