Possible September route

Should be quiet on my September trip as most of the European motorhomes are in England Scotland of Ireland :shock: (hope i've got the hang of this map uploading)

Heading over for Sept too , nothing planned better get out the map

Nice!
A few remarks. For free wild s:
The Belgium coast is a no go area for mororhomes, but you may like the old city of Gent For free wild places around, look at bipa.be.
Also, the southwest of Holland is not very welcoming. However, Middelburg is an old city (especially the town house). And at least this year, it has some stopovers. Driving from there to Dusseldorf, you might want to stop at Maastricht, a great old. cosy town. If you're lucky, you might assist at one of André Rieus concerts at the Vrijthof Place.Theres an expensive stopover i Maastricht itself, but just over the Belgian border (in Lanaken) you're free to stay.

Don't know when you were at Oostende, but check. Not sure, but I seem to remember the only stopover that was legal over there was closed some years ago.
As for Gent, we stayed for free at a parking next to the Watersportbaan. No services, but then again, it's free. It's got a bus stop to the town centre. Remember when the last bus goes, night bus doesn't go there. So we had to walk 3 kilometers when we were tired...
