h spending 20 hours in the air,
Its only 8 hours from Chicago, still a long flight.
visit some mothballed castles
After your 5th or 6th castle you'll have enough. They all start looking the same after awhile. Its interesting but also extremely boring.
You could go to Zakopane in the winter for skiing.
Or Sopot? They have Bars and a beach, not sure if they swim there bc of the freezing ass water.
It would be nice if "Professor Know it All" would tell us tourists all the exciting places to visit in Poland.
He doesnt know otherwise he would have been flapping his gums bragging about it.
Disney World
I hope your kidding...Woke Disney, they are one of the worst offenders.
