We are staying in the Sacred Valley and taking the train to Aguas Caliente at 8 in the morning. We then will visit Machu Picchu where we have arranged through our hotel a guide for 2 hours. We are staying the night in Aguas Caliente and then climbing Huayna Picchu at 7 am. Will we have enough time to explore if we are taking a 1:30 train back to Ollantaytambo? We are paying for 2 days of entrance fees so I want to make sure I leave us enough time. Thanks again everyone on here for all of your help!
