Polish Baltic coastal towns?

With the Mediterranean becoming unbearably hot in summer, the baltic coast will surely see a huge uptick in international visitors in the coming years.

I imagine that people will moan about gentrification as ordinary families are priced out from their favourite holiday spots. Lots of new condo blocks going up already.

The towns i have seen currently lack the sophistication of the best Mediterranean resorts, yet the scenery is just as beautiful. I hope that the whole place doesn't end up like Sunny Beach, Benidorm or Torremolinos, but theres probably enough space for all tastes.

I think the Baltic coast is a massively untapped resource for Poland and if they get it right it could be wonderful.
