First Time Camper - Where to go in Vendee with 2 toddlers?

Have booked ferry. Now need to book campsite pronto! Where is a good site to book a mobile home - 2 adults and 2 toddlers. Don%26#39;t want a location that%26#39;s too high rise or very touristy. Something a bit quieter with good pools and good restaurants nearby.

Thanks a million in advance.
