Anyone done it? I bought a three week ticket to Berlin right after Christmas. Plan on navigating the rail system through Prague and Vienna but I'm a bit stumped as to where to go from there; either east to Budapest and then back up possibly through Krakow, or west to Switzerland and then back through the heart of Germany.
I welcome any advice or suggestions anyone has about this part of the world and backpacking (i.e. traveling from city to city, just me and my backpack) in general.
