You might be traveling to a place where they don't all speak English. I was just on a two weeks trip around Europe and got to practice my secondary language skills in German, French, English and even a bit of Dutch/Flemish. I was never once taken for a one-language only arrogant tourist, but received a very good service everywhere. Can only recommend to pick up at least one secondary language.

They don't use PostNord up there, but have their own service for this: https://www.tusass.gl/en/organ...

In Denmark FM and DAB exist in parallel, but I assume that FM will be turned of eventually.
