Next month, we will arrive by train in Aguas Calientes at 8:43PM and plan to get up early the next morning to visit Machu Picchu. Ideally, early enough to get a ticket for Huayna Picchu.
We'll have spent the previous day in Cusco.
Since we wish to leave so early in the morning, is our only option to purchase entrance tickets for MP in Cusco? Is it also necessary to purchase the bus tickets in advance, or can we pick them up in the morning?
Finally, how early is it suggested to get in line to ensure one of the 400 spots? 4AM? 4:30AM?
