Ghastly overpricing!!
Sure, the convenience is neat, and the view of the ruins and surrounding mountains in nice -- but for $600 and more LESS per day, you can stay in a clean and nice hotel in the Urubamba Valley, down below... just a quick and scenic bus ride from Machu Picchu, after which you then can relax and explore the site, and adjoining Inca Trail, for several hours, to your heart's content. If you have money to burn, feel free to stay at the Sanctuary. But your Machu Picchu adventure isn't the least bit diminished by doing it economically. My brother and I know. We did it that way and saved a fortune! And we want to return again to Machu Picchu, and do it all over again the very same way. Our ages? We're both in our 60s. And were subjected to NO discomfort by going the economic route.
