I will be in Germany in early January and would like to know if there is an efficient way to get to Krakow from Nuremberg that would take us east through Prague instead of north through Berlin and Warsaw, or at best Dresden (that would take from 7:30am to 10:30pm). We will have rail passes for Germany, but most likely not for Poland and the CR because I know it is more affordable to buy tickets there and we are only making a trip in and out to see Auschwitz. Flying by any combination of airports is not cost effective for us but I believe buses might be useful. What would be the best way to find a bus or train that would save us time (versus a whole day of travel), or even allow us to enjoy Prague for an afternoon. Any answers are appreciated!
