They were very good, dependable, flexible, timely and well-organized. I definitely recommend this company!
Machu Picchu, Patagonia Glaciers, Iguazu falls and the lamb BBQ in Ushuaia
I'd change the flights schedule so to avoid too early in the morning or late night flights. I'd add one week to visit Galapagos islands and one week to go to Antartica. And I'd also change the guide in Rio de Janeiro.
