I'm guilty of it.
Whenever a long weekend comes around, I check Google Flights for cheap tickets from Krakow to another close-by European destination. After all, you can get from Krakow to Stockholm direct in under 2 hours for under $50/person round-trip. And when we were looking for a place to spend our fall break, we settled on Italy because flights to Bologna were only $75/person round-trip. Stupid cheap airfares, short flights - and just like that, you are in eating the most amazing kannelbular (cinnamon rolls) in Sweden or dancing in the medieval squares of Tuscan hill-top towns. We did this for our first two years in Krakow - nearly every break the kids had, we jetted off to another country. And it was fantastic.
