Vendee Region Sites

I know this is quite early but am interested in sites on the coast south of Nantes. The party will consist of 2 adults and 2 kids 11 and 14. I would like to be very close to beach or maximum 1/2 hours drive. The site would ideally have; outdoor swimming pool, indoor swimming pool, activities and clubhouse. Whilst I am not looking for noisy i understand it may go with wanting a site with things to do. I also intend tovisit a vineyard or 6.

If you have eperienced any sites that you could recommend that fit with the above criteria, I would very much apppreciate your comments.
