I think I have narrowed it down to:
Chateau Des Ormes (Dol de Bretange - this would be our only Brittany consideration for various reasons). Big site. Lots of onsite stuff. Is there lots of local stuff too (preferrably not all History)??? Has hte plus that it is 200km less driving cp to Vendee
Acapulco (St Jean de Monts)...good reviews...good complex....close to beach...loads of local family stuff how big is St Jean de monts (on a scale of Brighton-Weston Super-mare-Hastings...something I have heard of please)?
Le littoral (Sables d'olonne) I like the look of it but mixed reviews, not close to sandy beach.
But not averse to considering
Le Bois Masson (which i believe is very British)
La Bahamas beach (I quite like the idea of the little fishing village but complex is a lot smaller with fewer facilities)
L'Oceano D'or (which looks as though it has a bit more of a rural feel - although perhaps away from family stuff a bit?)
Can't do Les Biches or Garangeoire or Chaponnet as we can't do 10 days there.
Any comments on teh Camping Life Parks in Vendee welcome.
