Went with a History department program at school. I enjoyed the trip. It was pretty much just Krakow. But there's so much history just there and within short travel distance that I really wasn't disappointed. Hell, I loved that just about absolutely everything we did was withing walking distance!
Hm... 10 countrys overall... nothing to post here^^ It would be great do the selection a little more detailed. Because for example I've been nearly everywhere in Italy, from the tip of the boot to the austrian border and even on the Aeolian Islands
