Hello, I fly into Buenos Aires on a Friday next week and depart 16 days later out of Santiago. I plan on exploring BA that first week while taking a language course, and then flying down to Ushuaia for 2-4 days before flying back up to Santiago for a couple of days. But nothing is really set in stone except for my points of ingress/egress. I'm curious to hear anyone's suggestions on what they would do with a week in BA and another week split b/w Tierra del Fuego and/or Patagonia and Santiago. Thanks, Brian.
