Going to the substantial castle, (Castle Wawel) that stands on a big hill in Old Town today. Then to the Jewish Quarters to visit the Old Synagogue from the 15th century and to a museum or two. In the early evening I'm taking a fast train to Warsaw. I plan to only be in Warsaw for a day. I don't have a desire to go except to see the Warsaw Rising Museum and learn more about the tragic history of Warsaw during wartime.
