Hi all! I'm traveling to Cusco this summer. Doing a 3 day Machu Picchu tour which includes a sacred valley day tour that covers Pisac, Urubamba, Ollantaytambo, and Chinchero. Then we do the day hike to Machu Picchu and an overnight in Aguas Calientes. We're planning to stay in Cusco a few extra days after that to do the SHORT Rainbow Mountain hike (still a long drive starting at 5am) and now we're also interested in a day trip to Humantay Lake. This is already a lot of long, exhausting days and we're wondering if doubling back to the Sacred Valley to do the Moray ruins and Maras salt mines is worth it (money wise and energy wise). Should we sacrifice Humantay Lake? Any thoughts? Thanks!
