Trying to buy Machu Picchu tickets online for May 2015. The ticket website (machupicchu.gob.pe) is showing no tickets available. How far in advance can you buy Machu Picchu tickets? Can you buy a two day entrance ticket to Machu Picchu or do you have to buy two one day tickets? We would like to enter Machu Picchu in the afternoon and then go back first thing the next morning. Is it better to buy tickets from the official Machu Picchu website listed above or have a travel agent buy the tickets? Thanks!!
