IS MY PASSPORT VALID?

Two things to check: firstly, it needs to have at least six months’ validity remaining when you enter the EU — even if you’re only popping over for a couple of days. Secondly, it needs to have been issued less than ten years previously. It’s possible some passports that were renewed early may have had enough extra validity added so they fall foul of the ten-year rule. You can travel freely within the EU for up to 90 days in any 180 days, visa-free, for now, anyway.
