Cool, that's the way I figured it might turn out.
Thinkin I'll go Krakow-Budapest-Serbia-Croatia-Slovenia-Vienna-Prague-Bratislava. Been told to do the ferry between Vienna and Budapest though, so might tweak it a little bit and go to Budapest twice or something.
I'll probably be on here while I'm away for some in-journey travel tips. Seems like quite a popular part of the world
