Great trip. Beautiful archeological sites and cities included in the itinerary. Would have been helpful for many travelers to know that for the two nights at Machu Picchu you will need an overnight bag for the train ride and hotel stay as your luggage is likely too large for the train to Machu Picchu. Cusco was a great city to walk around and sample a lot of good restaurants.
Arturo was the best leader ever and would highly recommend him for the leader of the year. The trip was varied and taught be so much. Definitely ( if you can!) go to Inti Raymi. The most spectacular event I have ever seen
The Amazon extension was well worth the money as stayed in superb lodges with excellent food
