There was a post earlier today complaining about questions that aren’t open-ended, and therefore don’t adhere to the community rules. So here we are with a question with many possible answers (which makes it properly open-ended).

I mean - if you’ve been to Switzerland you know the answer is Switzerland.

OP is a close relative of “Hey everyone, I have 5 days to visit Europe, what’s the best route to see everything?”

Reading the title, I would presume OP wants someone from one of those over 40 nations in Europe to say where tourists should avoid at all costs.
