One of my best vacations. Our guide, Fernando, was fantastic. Caring, warm and beyond knowledgeable. He’s the best. I would, however, have liked another day in Buenos Aires. Wanted to just walk the city leisurely. Same with Rio de Janeiro. Needed some time to explore Copacabana and Ipinema. Did not like the hotel in Bariloche or the hotel at Iguassu Falls. We returned to the hotel at Iguassu Falls at about 2PM & our room was not made up yet. Not able to relax until I called the front desk & someone finally came up to clean the room. The water in the bathroom sink in the hotel in Bariloch went down very slowly. Not a nice sight. Also neither hotels had tissues in the rooms.
