The plan is starting to come together

So...I will be traveling around Eastern Europe for a month. I am super excited to do this. I have been needing to travel. I have been doing a bit of it around the good old USA. Moving to the west coast has sort of felt like a vacation, and I have been back and forth between here, Miami, St. Louis, Austin, Alabama. But I am in the need for some culture shock ... which I don't think will happen to me, but a complete change in scenery and perception are the main goals.
The plan so far:
-Fly into Berlin, hang out there for a few days, try to gather some info.
-Get to the Polish border and catch a train up to the Baltic coast, maybe around Gdansk.
-From there, head south to Warsaw, Krakow, any cool spots in between.
-Keep moving South into Slovakia through to Hungary.
-Get in tune with some Medieval towns then head to Budapest for some public hot spring action
-Get to the Czech Republic, see the bone monastery (Kutna Hora). Revisit Prague, get into rural Czech Republic, maybe see Austria
-Head back into Germany from there, try to hit Munich, Cologne, anywhere else we can before returning to Berlin.
-All in one month's time.
