mountie...don't let the current economic issues in Argentina dissuade you from planning a visit. Obviously, if you buy your ground package through Luxury Link you will peg those costs in USDs. Once you get in country, try to exchange only minimal amounts of USDs to pesos. During our last trip, we found that most restaurants were more than happy to accept USDs (in cash of course) at a more favorable exchange rate than that posted as 'Official.' If you are planning to travel any time soon, you should be able to get at least 30% - 50% more using this approach (remember, check your bills to make certain they are in good condition....we ask our bank for new bills and check for tears and marks). Don't deal with currency traders on the street!
