I drove through Slovinia a couple of years ago. Going between Vienna, Austria and Venice, Italy,
I found the people to be very nice and helpful, even the border guards. English speaking was never a big problem - in fact better than Germany or France.
But the areas I travelled were not booming industrial or sight seeing areas. You could tell they are still recovering from being a Soviet satellite.
Certainly would be an interesting vacation area some summer. You could live like a king on vacation for not too much money. Just don’t expect as many big sights like Paris or Prague.
“Just don’t expect as many big sights like Paris or Prague.”
It seems to have much to offer for those who prefer an area’s natural beauty.
The mountains, lakes and small towns and villages are what would draw some.
