Well yeah, there might be some exceptions. But in a 4° world, economic collapse is very likely, and tourism would be one of the first industries to die out. Antarctica has no soil to speak of, so not exactly a good place to settle. The most northerly lands will indeed be interesting to settle in at some point, though I wonder how long the adjustment period would be (e.g. as long as the permafrost is melting, the ground will be unstable)
