Hi Linda,
I don't know if you read my review of this holiday; if you haven't you might find it helpful. This is an expensive tour, but absolutely worth it -South America is always a pricey destination, but you see and do so much on this holiday and there was a highlight every day! If you have any questions regarding the tour, I'd be very happy to answer them. I did it with Travelpshere (as JY only did Argentina and Brazil at that time) and the extended itinerary including Chile and Mendoza is a much better option - I do hope you book for 2015 when the dates become available. I still can't believe I travelled over the top of the Andes!
All the best,
Bob
