I have been visiting Weerterbergen Park from the UK for many years now and always enjoy my visits there.
In the past, booking could be difficult however now it is so easy to book online, and there are plenty good deals to be had. The website is now in English too, but can be navigated even in Dutch if needs be. It is easy to identify the holiday and pay, either in full or in part if desired, and communication by email is great.
