We are thinking of Brittany as this years holiday destination. Looking for 1st week of August for 2 adults and 2 teens. Would prefer somewhere near the beach , relatively quiet. Have been to Center Parcs in France before so looking for something similar. All the campsites I look at with mobile homes or chalet seem to be plugging the toddler friendly thing - are these campsites geared to families with young children or would there be stuff for teens to do? Any suggestions??
