There is a decent Huttopia site in Versailles. Its on the outskirts but an easy bus ride up to the palace. We had a great day out there, especially enjoying cycling round the massive grounds and visiting all the extra parts as well as the main palace. Definitely worth a trip.So if you've visited Versailles I salute you, definitely somewhere we will return too but after I've done some research on parking and entrance costs and best time to visit, which I'm guessing isn't Friday afternoons.
