Our current plan is to fly to BA and spend 4 days there (including attending a futbol game);
Fly to Iguazu Falls (how long to stay???)
Fly to El Califate (on to Torres del Paine for a week- hiking the "W")
A couple days in El Califate and 4 in Chalten.
5 days in Bariloche.
5 days in/near Mendoza.
Fly out of Santiago.
Question: Is there anything we're missing that we really need to see? We'd like to visit Salta, too, but just don't have the time.
