Argentina, Chile & Brazil Tour Review: Buenos Aires, Bariloche, Iguazu Falls, Glacier Cruise

We would not stay at the hotel in Puerto Iguazú. Due to being in the rain forest, there seemed to be a lot of mold in the buildings. And their food was not very good. 
Our only other complaint was about about the transportation. Some of the vehicles used for our excursions or tours were too small for 4 people and therefore uncomfortable for long rides, especially the trip to Torres del Paine.  The guides were great though.
