Hey, i'm going to be traveling from Lima to Cusco, then to Copacabana then La Paz. I was trying to figure out what buses to take/hostels and decided that maybe actual people know more than google ai. I want to travel cheaply but not dangerously so. What buses do you guys recommend for that trip? I saw the superciva one on busbud and was wondering if anyone used it or did that trip and has some information to impart unto a new traveler. All help appreciated!
