Hi: We are planning a trip to Poland from the East Coast and we are considering approximately 10-12 nights on the ground. Since direct flights arrive in Warsaw we were thinking of doing Warsaw (3-4 nights), Wroclaw (3) and Krakow for (4). Then taking a train back to Warsaw for direct flight to NY area. Besides Auschwitz are there any must see sites? I heard about salt mines, etc.
Any tips or advice would be appreciated.
