Campsites/Gites near Royan/La Palmre

Could anyone please recommend a campsite/gite near Royan/La Palmyre region in France for a family of 6. 2 adults, 1 15-year old; 12-year old; 8-year old and 2 year old. Mixed ages so a good balance of activities, shops and restaurants, etc. nearby would be great. Would love the space of a Gite but almost all I have seen are way out in the sticks. 15-year old and parents would go little cabin crazy after a few days me thinks. Campsites look good for entertainment factor but don't know if cooped up in a place no bigger than a shed for two weeks would mean that we would be coming home stress-free and relaxed after two weeks in the (hopefully) sun. Any suggestions greatly appreciated!
