Are Finnish families flying to the Mediterranean and the Canary Islands for culture or for a beach vacation? I'm guessing the latter. And to replicate this, Americans don't need to leave the US - they can fly to south Florida any time of year, and a bunch of other places like California during the summer.

Americans travel a bunch, and I'm not convinced they travel shorter distances than Europeans. It's just because the country's so big, it's not international.
