Right, but that was mostly the issue of all the former Yugoslavia nations.
Czechs 1) were not a part of Yugoslavia 2) have a long tradition of visiting the Adriatic sea.
They are not poor anymore, and can afford it.
The price increase in Croatia in the last few years is insane, especially near the tourist spots (= seaside). Czech people who want to save some money now usually turn to the other Balkan countries that are still quite cheap.
Not really. They are not poor anymore, and can afford it. But quality is just not there compared to Italy, Greece, Egypt...
Only benefit for Polish and Czech tourist, they understand local language.
