Upon arrival, there was a note with a phone number. The manager arrived within two minutes. All the pitches were closed off. Free choice wasn't allowed, even though there were no reservations. German guests were allowed to choose later, Dutch guests weren't. A very unfriendly welcome, and I had to pay €40 immediately. Also: no response to my email from two weeks ago. Absolutely not recommended. Everything was unpleasant. Never again.
