Using Crypto While Traveling

I'm looking at going down to South America and would prefer to use crypto to get cash while I'm traveling. I can't find any sites similar to localcryptos to find local sellers, does anyone know any sites to buy/sell crypto in person? I figure I'll load my wallet before I go and then get cash as soon as I arrive in Cartagena or Lima.

Has anyone traveled with crypto recently? if so how'd you pull it off? feels like it would've been easier to do a few years ago. the only on/off ramps I can find anymore are all through bank accounts, Zelle, Wire transfer, etc.
