OK, the campsite has pitches for tents and touring caravans, also hosts Canvas, Keycamp, Eurocamp etc. They also have their own chalets Duingalows.....these work out as more expensive than the Cravan option, but they do have a bit more living space.
OK first things first the site is big with around 2000 or so pitches/vans etc. The water park is excellent and is free for 2 hours from 10 till 2. The slides run from the gentle lazy river to the scary Blitz and Flitz whic scare my dh and he used to be a fighter pilot! There are 6 water slides/ shutes, two that you do down in a mini boat (one in the dark), two slides that end in a funnel that you shoot around and the lasy river. there are series of pools, the largest of which has a wave machine. the pools are not that big. the slides are the real thing. Perfect for your age boys!
The theme park is also good fun, but not full of white knuckle rides. there is still plenty for your age kids to do, the 12 year old might find some of them take but there is Mad Mill, Splash and a another thrill ride to keep him happy. The themem park is free all day, every day.
We wentinto the water park every morning, canme back to the van for lunch and then went into the theme park inthe afternoon.
You can hire bikes and go carts....out two loved this and would entertain themselves for hours riding round the park.
We go on the channel tunnel, as we are crap sailors. Hoinf Harwich/ hook of holland cuts the drive in holland to 30 mins but adds to the cost.
Food. There are snack bars on site. there are also two resturants which are OK but not great. We stop in cite Europe in Calais and stock up, tbh. there is a shop on site which is OK but not a massive range.
It is great fun. We have now been three times and wil go again next year. the kids talk about it more than Eurodisney if I am honest!
Any more questions, let me know.
