I'm planning a tip my friend and our planned route is: Dubrovnik - Budva - Bar - Belgrade - Budapest - Bratislava - Wien - Krakow - Prague. We'd be using trains and busses and we are planning to do it in 17 days (or maybe 20). We are not planning to stay overnight in Belgrade, Bar or Bratislava. I'd love to hear any comments for this plan and recommendations as well. Are we totally crazy even thinking we can do it in 17 days. Has anyone done a similar route? Thanks!
