The statement is - True.
Slovakia is a Central European country that in the past couple of decades has invested a lot in its thermal springs and made them profitable tourist attraction for both its own citizens and the foreigners.
The country made a nice plan about the usage of the thermal springs, and big portion of them were used for building spas, wellness centers, and modern water parks. That has brought in a lot of tourists to the country, and made it the most profitable tourist attraction in the country, which resulted in further investments and modernization.
