Well I took about 10 days to make my mind up and it us now full. The site are suggesting LE Bois Tordu. Any other suggestions welcome

For future reference I can briefly comment on Clarys Plage. Whilst holidaying in France at St Jean de Monts 2 years ago (this summer) we had a wander round this site and it did look really good and all the mobiles looked in good condition. Some close friends went there last year during the school summer holidays and they were a little disappointed. There was a lot of teenagers causing a nuisance.

My understanding is that this site does get booked up very early and is very popular. Perhaps it was just the people there at that time.

Good luck!
