We do loads of camping and have thought about going to a site, maybe France or Spain, where we could have a pre-erected tent, as the kids are tired of our uncomfortable sleeping mats. However we want a site that isn't heaving with kids and allows a bit of space and privacy between pitches. A big ask but any suggestions?

most of the sites we have been on in france are well spaced out try any in brittany and northern part of france small sites are less busy there is a nice one in gulvec right on a nice beach ideal for the kids and lots of shade, and not to far to walk to the village you could walk round on the beach.

thanks, will check it out

Have a look at http://www.ukcampsite.co.uk/sites/ - you can search for sites in Europe and the forum on there is really good for asking this sort of question. We camped in France for 3 weeks last year but we had our own tent and we stayed on small sites so none of them had the sort of thing you're after.
