I saw on the website that you can only purchase student tickets through travel agents / in person for Huayna Picchu. Is there any way around this? Is it possible to get a friend already in Cuzco to purchase a student ticket for me or do I have to buy it in person? I am trying to avoid the markup on the ticket. Are there any friendly travel agents who will not charge a fee for student tickets? Can I purchase an adult ticket and get a partial refund after showing my student ID card?
