Flights on KLM from New York, San Francisco and Washington, D.C., to Krakow, Poland are available for only $519 round-trip for travel in September and October.
Krakow (the final W is pronounced like V) is the “fun city” in Poland. Its huge central square is full of people milling about after dark, and the cafes surrounding the square are full of people watching the square full of people. If you purchase a coffee, beer or other beverage you can sit there for hours without being bothered by the waitstaff, unlike in the United States.
