Lima, Cuzco, all over really because of this class trip. Any recommendations?

Don't forget to check out the Salinas de Maras from my photo when you get to Cusco, they are really amazing!
If you are looking for another cool place to go, I can recommend Huaraz, amazing Andean landscape!

That's basically where I've been. And Machu Picchu but I assume if you're going to Cuzco you'll be heading there. It's amazing!
