I have two back-to back tours in Eastern Europe with two free days and nights between them. Tour one begins in Helsinki, goes through Estonia, Latvia, Lithuania, Warsaw, Krakow, Wieliczka salt mines and Auschwitz. On the third day following this tour, the second tour begins in Prague then goes to Slovakia, Hungry and Budapest. How would you recommend I spend my free days? I could stay an additional night in Krakow and one in Prague, go to Nowa huta, Boleslawiec, etc.
Thank you!
