Overall we had a really good time. Peru was probably the highlight for us. The guides and the people were very friendly and attentive. The sites we visited were very interesting. Having only travelled in relatively wealthy regions before it was a little confronting to see the poverty of some of the people and it made us realize that we are very fortunate to live in Australia. We were lucky not to have been caught up in the problems at Machu Picchu. Given the very difficult terrain that the train and roads pass through it is understandable that flooding in the valley could cause the problems that occurred. We had some minor landslides as we went out via the Andean Explorer to return to Cusco. That trip was more than 13 hours. The trip to Inkaterra was great and the eco lodge was very well set up and managed. The tree top walk was a highlight as was the actual boat ride to get there. Argentina and Calafate were great. Seeing the glaciers and going on the boat trip was very good. Damain was a great guide and made us feel very welcome in Buenos Aires. It is interesting to compare the size of the cities and the general standard of the public infrastructure to Perth. The waterfalls were well worth seeing and the boat trip up to the base of some of these was fun. I took a lot of pictures and will be able to use some of these in future geography textbooks. We were impressed by the organization and the way the system worked with someone to meet us at each point. I would not like to travel first up into South America without this support. As you mentioned the planes are not that reliable. It is probably not a good idea to schedule connecting flights. We were lucky on the connect to Lima from Calafate. Our luck ran out when we went from Lima to Sao Paulo with TAM. That made the connect to Rio a problem. It was also the same when we came back to Australia. Interesting to compare the responses. We spent about 5 hours in the airport in Sao Paulo while they sorted out our luggage and accommodation and new flights. In Sydney we were met by a Qantas rep with details of new flights and accommodation as we stepped of the plane from Buenos Aires. All in all we had a great time and the organization was excellent from your end. Your suggestions of locations was very good. I will CC this to Diane so that she can make her own comments. I am still trying to get back into local time and am writing this at midnight in Perth.
