I am planning a return trip from Sydney.  Fly via Santiago de Chile to a hotel in Torres del Paine National Park.  Group day hikes in the park.  Overland to Ushuaia and join a return cruise + hike to South Atlantic islands.  Fly to Valparaiso and join a one way cruise via South Pacific islands to Sydney.  I have spent most of my life leading other peoples' kids on excursions.  This will probably be my last big trip.  Past phases of life included rowing, sailing, scuba diving, ski touring, bicycle touring, and now day bushwalks with a caravan instead of a tent.  What's wrong with me?  I guess that will depend on your bias!
