I was thinking of going to Argentina later this year. Would that be a bad idea?
There were a few annoyances, such as the different exchange rates and it being nearly impossible to buy a subway pass, but otherwise no more challenging than anywhere else.
The two of relevance to someone visiting from the US on vacation are the "blue dollar" (a black market exchange rate that's basically double the official rate) and the MEP rate (exchange rate used by some, but not all, purchases on American credit cards).
