Since the Corona Motorhome registration boom, there are ever more motorhome/campervans finding unauthorized spots to park overnight for free, because the motorhome rule says, once you fork out 80k € for a Motorhome/Campervan, you should never spend a penny for a site. Ever! Holidays will be a lot more relaxing when , instead of parking overnight in a paid site (with toilets, showers, grass to park and set your table in for a nice dinner/breakfast, nice view) one parks unauthorized on a street, or a parking lot prohibited for MH, with the risk of been told to move in the middle of the night, or finding a fine which usually exceeds the cost of a pitch. No facilities, just tarmac. Wouldn't your kids love it? Lots of resident being pissed too, having their street used as a camping spot, what would they do to your MH once they can't take it anymore?
Plenty of MH parking spots for less than 20€ a night total (multiple apps to find them and book), many many sites below 30/35€. If that is breaking the budget for the hol, than buying a MH or Campervan wasn't a wise move.
Bottom line, unauthorised overnighting lead to even more strict enforcement and parking prohibition.
