We have been to la Garangeoire. The dcs loved it and we want to go back to similar in Brittany or Vendee. We have a limited budget so are looking on the Matthews type sites rather than Key Camp and Canvas Hols end of the market.
Our wish list includes:
Me - close to pretty french town or village with nice cafes
Dh - a shop and a bar
DS1 - table tennis, pool table, other teenagers
Ds2 - walking distance to a beach
So, we're not asking for too much really! 
Can anyone recommend anywhere?
