Manchu Picchu

So I'm really bummed right now. The group I signed up to go on the hike Manchu Picchu is full. Can you F-ing believe it? I have a non-refundable plane ticket, and the other 7 girls got into the tour group hiking up to Manchu Picchu. I'm trying to decide if I should still go by myself. Anyone out there want to go to hike Manchu Pichu with me? I'm so f-ing bummed. Four day hike. Should be an experience of a lifetime. Anyone??? I don't know what to do. What would you do?
