Wanted to see Berlin, Elbe river towns, Prague, Krakow and Warsaw. Viking cruise directors, guides and staff were brilliant. They took the time to make all guests feel wanted and comfortable. Loved all the wines served by Viking and their meals were superb. Hotels selected by Viking for pre and post cruise visits were excellent. All the tours were first class, and gave everyone understanding of what life was like in Berlin and East Germany during and after the Second World War. The visit to Auschwitz was extremely sad, but necessary to clearly understand the Holocaust. Everyone who has any doubts about the Holocaust should visit Auschwitz to clarify any uncertainty in their minds about the inhumanity of the Nazis. It was also remarkable to see the beauty of Warsaw, since it has been totally rebuilt by the Polish people after Hitler totally destroyed the city. Finally, Prague and Krakow are two of the most beautiful cities on earth! Their town centers are remarkable!
