Trying to work out whether Portugal is workable at the moment, because the rules I find online contradict each other.

Photograph everything before you open it. It takes ten seconds and settles most disputes.

The address matters more than the contents after a while, and nobody warns you about that.

A card that works domestically can fail on an international merchant for dull, uninteresting, entirely legitimate reasons.

A written confirmation email after every phone call is the cheapest insurance there is.

Happy to hear I am overthinking it.
