This is one place where a juicy steak washed down with wine isn't an extravagance. The U.S. dollar has been strong against the Argentine peso in recent years, but there are plenty of ways to lose that advantage if you're not careful. Try to keep small bills on hand, as vendors and taxi drivers won't break large bills -- or may even switch your good bill for one of the abundant counterfeit ones. Watch out for pickpockets seeking money and cell phones. There are inexpensive lodging options -- even a Days Inn in Buenos Aires. Renting an apartment is a valid option for longer stays. To explore Patagonia or the Pampas on the cheap, try campgrounds, often cheaper than hostels or even free in some national parks.
