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)

That’s pretty close to this summer

Yeah, I’d be quite surprised to see large increases in tourism anywhere in a +4° world…
