It turns out there's a website for that, they list locations, (some) fees and network operator websites. There are hundreds of them just about everywhere. Lightning ATMs are available in some places. If you download their app, they give you a better search experience.

Think on the other way. You go to a country and you need local money. All you do is sell btc and withdraw fiat (although the wolrd is moving to all digital money). My parents went to Europe and after dinner they asked them for fiat (no credit or debit). They discuss like half an hour. Also some Taxis or UBER in Latam do not accept anything but local currencies.
