However, if you are feeling the pull of the North Pole World Expeditions are offering a rare deal of free charter flights worth £500 on their June 29 departure. The flights are from Brussels to the isolated island of Spitzbergen where the human and polar bear population are equal, and which your cruise will circumnavigate for 9 days. When you’re not being ferried to shore by zodiac to explore the fjords, glaciers and cliffs and wildlife you can enjoy topical lectures on board and all included meals. At £3000 it’s not exactly dirt cheap, but by Arctic standards it’s a bargain. To book see www.worldexpeditions.co.uk or call 0800 0744 135.
