This is a complicated question, my apologies! I love the polar regions and have explored the North and South, the most recent one being Antarctica which was incredible. This year I have a limited travel budget, and I'm wondering if I should do Svalbard (circumnavigation on Quark) or Churchill to view the polar bears. I would like to get as close as possible, and also view other Arctic wildlife, like foxes, walruses and birds. In terms of budget, which do you recommend?
