Doug, by all means do a Tango Show in Buenos Aires and go to the Recoleta Cemetery and find Eva Peron's grave. Don't miss the Penguin colonys in the Falkland Islands and drop in the Globe Tavern in Port Stanley for a Bodington's or two (or more) :D . In Ushuaia, take the "Train to the End of the World" -- it's both fun and educational. If you have time in Valpariso, go to the Concha y Toro Winery (which is really closer to Santiago)--it's a beautiful place and they have some fabulous wines.
