My wife is in a large FB group which tries to find more sites for Campervan/motorhome to park for the night for payment..the continent has thousands of them and they are called Aires...most are in the middle of towns or on farms or anywhere you can park a van.They are now getting more popular in the UK as a way of bringing money into the local area’s businesses.What we have now noticed is many of the sites are now including their 3word address as are many people in the camping/caravan world.
