Hello! I will be in Czech Republic in July for genealogical research as well as a bit of historical study. My plan is to spend about 5 days in Prague and surrounding areas, and then to go to Poland for the last leg of the trip. I'll be flying back to the US from Krakow. The point of the Poland trip is to visit various concentration camps where my family were during the war. Specifically, I plan on seeing Auschwitz and Majdanek camps. The problem is the travel part from Czech Republic to Poland. It seems to make sense to take a train, but the trip from Prague to Lublin is probably pretty long. With the finite amount of time I have, what's the best way to do this? Thanks very much for your help and please let me know if I've left out any necessary details. Thanks again.
