Yes. Fully covered Brazil. Argentina , Chile upto Ushuaia which is the gateway to the Antarctic.
There's a small ship tour to the Antarctic, but takes a week . At that time our son was year 11 and that limited our time. So had to skip it.
We covered the Amazon from both Brazil and Peru.. Finished our trip after Machu Picchu.
Whenever you need say the duration and the places then we can decide. It's my wife who does all the planning. Not me
Platagonian icefields are one of the best sights. Perito Moreno Glacier just to name one.
Also spend a night in Torres Del Paines National Park.
