If you haven't bought your tickets for the bus to Machu Picchu, make sure you wake up early if you want to check out Waina Pichu which only allows 200 people per day to hike it. Plan to be in line for the bus at 4:45am at least, if you have more than 2 people split yourselves off, 1 group buys the tickets for the bus and the other group waits in line for the bus. Believe me the lines will be long, long before 5:00am.**Make sure the person buying the tickets has everyones passports or ID's for purchasing the bus tickets to Machu Picchu, tickets cost $5.50 one way...TRUST ME you don't want to walk it.
