Sites In North Vendee

Please could you recommend sites in Vendee, preferably towards the north end. We are looking to go August with 2 adults and 2 kids, boy aged 14 (footballmad) and girl aged 11. I would like the following:

Good day time and evening activities and entertainment. Good swimming pools, on or within 30mins of beach. Good sized pitch's. Preferably sites where they enforce noise curefew after, say, 11pm

We intend to balance time between site, site-seeing (vineyards mainly - Hic! )and beach.

I have looked at quite a few but would like recommendations from your personal experience.
