I can't think of a single country (other than my own, and maybe in the rest of the EU) where I've gone to a hotel and not had to give my passport and credit card. Passport is photocopied, credit card is checked. Passport number is like a US social security number, it's public information.

I don't think I've ever not been asked for my passport (or some other form of government ID) when staying in hotels in the EU. Two weeks ago I stayed at a large chain and I was asked for passports of my whole family.

Been a while since I stayed in the EU, but I was in Brussels in October 2019 and stayed at an Aloft at the time of an EU summit. I distinctly remember remonstrating with the clerk about the embarrassment of my British passport when I handed it over.
