Argentina & Brazil Luxury Travel Review; El Calafate, El Chalten, Buenos Aires, Iguazu Falls Boat Ride, Moreno Glacier

We enjoyed our trip very much. After spending 3 days in Buenos Aires on our own, we flew down to El Calafate in Patagonia. Our first day there included a guide who took us to the Perida Moreno glacier which was amazing. It was a spectacular day. We had no plans scheduled for our second day because we were hoping to trek on the glacier but found out there is an age limit for that and we're too old. With little else to do, we took a boat ride to look at the other glaciers. Whereas it was a pleasant day, it was more of the same of what we did the day before. We would have liked to have had a different experience.  From El Calafate, we had a driver pick us up and drive us to El Chalten. This was another incredibly beautiful spot. We hiked there for a day and a half which was plenty. 
We then flew from Patagonia to the Iguazu Falls. This also was a spectacular experience. We especially enjoyed the boat ride to the falls. You do in fact get a shower.
Overall, our guides were great. Everyone spoke English and they were very helpful.
