Hi, my name is Siv and next year I going to travel to Argentina on my own for the first time. I'v been to Bolivia but with an organisation that arranged everything for me. So I am appealing to anyone who has travelled on their own or with a friend in South America really. I just would like to know whether or not its easier to get out there and book up tour and treks, and how much it's like to cost me for 1 and a half months of travel. Much appreciated, Silv
