I frequently camp in Europe, and many cities over there have a good solution to the many thousands of campervans that visit popular cities.
They give night rates in the city car parks, and it’s usually about $10-$15 a night from 6pm to 6am (though this can vary).
It not only brings visitors to somewhere they can spend money, but it is a lucrative cash cow for councils. As a ‘movanner’ myself, I would not mind paying it.
