I am surprised at what seems to be a reluctance to travel far for the Poles
Poles actually travel a lot but more so abroad like to Turkey, Bulgaria, Egypt, Thailand, Spain, France, Germany, etc. Even like people who aren't making a killing like say your average taxi driver or maid will take vacations abroad since the tickets are cheap. A lot of Pol-Ams will go to Poland then buy tickets for a flight to another country to visit as its way cheaper.
Krakow is beautiful - it's the cultural capital of Poland. See Wawel Castle first and foremost.
Zakopane isn't too far either like 2 hours from Krakow and it's worth visiting especially if you're into mountains, winter sports,. It's like a Polish Aspen, Colorado or mini Basel without the watch industry.
