Huttopia at Versailles (and the other Huttopia sites) don't accept Camping Cheques any more. Shame, as we liked the sites - we've stayed at Huttopia Rambouillet and Huttopoia Senonches - also both in woodland, but with open areas, and lovely washblocks and central facilities. Senonches, especially, has a lovely lake and the restaurant and bar area has a terrace directly over the lake - lovely at sundown!
I'd generally recommend the Huttopia sites - and we'll be going back even if we have to pay 'full price'!
