We've not camped in Potsdam but very close by.
What a fabulous place with all its Palaces.
We moved there from a campsite to the south east of Berlin (near a big lake), which we found was easier to visit the Capital from as there were many Park and Ride trains nearby. The campsite management were particularly helpful by providing us with a comprehensive map and excellent instructions on getting to the railway station car park.
Are you doing other places? If so I the east we strongly recommend Dresden and Colditz which is close by. Also Lutherstadt Wittenberg.
Any where else please ask and we'll see what we can do.

Hi Geoff. Apart from the first site abroad, we don't bother to book others and we've only once been turned away because they were full. That's in 13 years.

Normally the ACSI "Acceptance Period" doesn't apply from early July through August.

Almost all countries consider anytime other than the above dates as "Low Season." The two exceptions are Germany and Austria and each "State" (Department) in those countries has different Holy Days. We had a laugh with a young German Family when we were camping near Nuremburg and only managed to squeeze into a campsite overflow field in June. When we asked them which Saint they were celebrating, thier answer was "we don't know and who cares, we call them Happy Cadaver days"

Take a look a this example of a German ACSI campsite https://www.campingcard.co.uk/germany/rh...agmuhle-102119/

If you pan down the page to the "Acceptance Period" the dates in white squares are not periods where you can benefit from ACSI. This will apply to any ACSI site you will look up throughtout Europe. Note also the Average Rating number in the orange square beside the photograph. We try not to go to a campsite that has less than a 7.5 rating as there is normally plenty of choice.

Also please note that if you are planning an ACSI based trip for next year, the campsites may still be there but the numbers will be different. The campsite I've used as an example is ACSI 620 this year (see number in blue oval shape in orange band.)
