Travel Review: Luxury South America Vacation, Chile, Argentina, Buenos Aires, Patagonia, Torres del Paine, Glacier Tours, Hiking

I would spend less time in Buenos Aires, maybe 2 days instead of 5. I would upgrade the city hotels (not my favorite part), and request the largest room at Torres del Paine I would definitely do more intense questioning of the travel agent on the actual difficulty and time required for hikes.  Patagonia estimates in general, for time to complete a hike are optimistic at best.  We are in reasonably good shape but the hiking times seemed to be off by at least 1/3 (8 hours was generally 11 or 12).  One of the trips required rock climbing, without gear, which was not only frightening, but dangerous, something I would like to know in advance.  So I think I would request a very thorough vetting of each hike and excursion next time.
