I have 30+ days to get from Prague to Instabul. Suggested itineraries appreciated. Here's what we're thinking:
Prague, Budapest, Vienna, Zagreb, Split, Dubrovnik, Kotor, sofia, instanbul.
Personally, I wouldn't waste time in Zagreb. I was on a two month trip through Europe and was in Rijeka and Zagreb. Sadly, didn't have time to make it down to Split. But seriously, there isn't anything nice to say about Zagreb aesthetically. People were very friendly though!
