Sorry for the very late reply. All went well except for the exit from Cusco. My daughter wanted to go to a really upscale restaurant in Lima, and because we missed the right plane and the next plane arrived too late we could not do that.
Next day she had made plans to go to the sand dunes further south and dinner that day was out of question.
Over all the trip was good. We both enjoyed it and quite possible will visit Peru in a year or two. All our guides were excellent. I have plans to take my son to Manchu possibly in Early summer after the rains. Just need to see when he would be free.
