I'm a student myself and I recommend you figure out your finances before planning this trip. You have to think of the hotel/motel/hostel and food cost. If you're like me and read a lot of Trip Reports on FT then don't even think of staying at the Park Hyatt Buenos Aires for example unless you come from a wealthy family or have a lot of Hyatt points to splurge on. Just my two cents on this. But good luck if you figure out the finances!
