Pokorny suggested experiencing slow life in the Czech Republic. "Travel doesn't have to be in a hurry. Find a chair on the streets of Brno to relax, or spend 20 to 30 minutes in a century-old café with a cup of coffee and dessert to truly feel the local culture."

Kelemen recommended Hungary as a year-round destination. "Budapest's Danube scenery, more than 150 thermal resources – you can nourish your health in winter and visit Lake Balaton in summer."

As the largest of the four, Poland advocates long-stay in-depth travel. "From the Baltic Sea scenery to the historical buildings in Warsaw and Krakow, each city offers unique experiences," Gumienna said.
