We are visiting from Australia soon. We are travelling around the country from north to south in our own transportation. It is suggested that we bring US dollars to convert in shops/restaurants etc. I don't feel safe carrying lots of cash on me, at the best of times in Australia! Is this the done thing these days with tourists travelling in Argentina? Is no one using credit cards or travel cards anymore because of the rate difference? I imagine that would make them prime targets for an armed robbery/theft??? For a long trip, people would need to carry thousands of dollars..
