We booked direct with Duinrell, as at the time of booking, it was cheaper than Eurocamp. We opted to get a small Duingalow (static home type bungalow). So glad we did, because the Eurocamp accommodation was really on top of each other, whereas the Duinaglow had a nice bit of outdoor space for the kids when they weren't in the park.
Duinrell Theme Park itself was better than we had expected, the rollercoasters and rides were great fun, for all of our family (children 10yr & 7yr). The site felt so secure, even the kids at that age could go off and do their own thing, go on their own choice of rides and have some independence, not forgetting giving us some peace!
Tiki-Bad Water Park was great! Some seriously good water slides here and plenty of fun for all four of us. There are quite a few queues for the slides though so expect to be inside for 4 hours or so if you wanted to try everything. Changing rooms could use some improvement. There's not nearly enough family changing spaces so the changing/locker spaces were carnage!
The food market on site had a good choice of foods and things you may need for your stay. Though we opted to stock up on a weeks worth of food from a local supermarket as the prices were more favourable. I think had we been using the restaurants or little deli trucks around the park, we'd have spent a small fortune.
We did check out the camping facilities while we were there, as we'd likely return here as it was so good. The camping facilities and laundry areas were in really good condition. Strengthening the argument that we could on day come back and camp.
Overall, what an amazing stay we had, incredible memories made for all of us and we've already been recommending it to our friends.
