Don't go you'll hate it....
We hate it that much we are going back for the 5th time this year!
Lovely beaches on the south / west side, miles and miles of dedicated flat cycle tracks away from traffic, fantastic food markets, good range of eateries including little pop up places at the oyster farms in the summer, lots of villages to visit that all have their own character and markets.
We have stayed at Sunelia Interlude near LeBois Plage the last 2 times we have been which is a large site next to a good beach.Good for families. LeBois / La Couarde is a good area to be as you are fairly central so can cycle to most places without moving the van. Definitely worth taking bikes as the whole place is so geared to riding them.
