The representatives in Peru were amazing. The rep in Iguazu (Edber) was the best of the lot. He was informative, funny and arranged a fabulous night of entertainment for us. He also got out luggage checked in early so that we could go to the bird park rather than wasting time sitting at the airport.
The guide in Rio was also very good. Again he was informative, funny and very respective of our needs.
Overall a fantastic trip. Local agents were excellent. Very well contructed itinerary. Fixed points but also free time for us to revisit Machu Picchu and walk around Cuzco on our own. We liked the small nature of the hotels and all had good locations. Overall a great trip, just need to decide where to go to next.
