Hi,
we stayed in Le domaine de drancourt in August last year as part of a 3 centre keycamp holiday.
Of the 3 sites we stayed on, this one was the least exciting.
St Vallery its self is beautiful, and there are lost of surrounding lovely seaside towns (as well as the obvious war grave sites), but the campsite itself, whilst clean and well kept is a bit dull.
Perhaps we found it that because we went with our 3 kids, and the weather wasn't good, plus, we had spent a previous scorching hot week in Berney Riviera, which is a fantastic huge site!
We found the restaurant disapointing in Le domaine de drancourt, and the bar only opened at 8.00pm and didn't allow children!
I suppose it depends what type of holiday you want. If you want something pieceful, then this is your place, but with 3 kids in tow, no thanks!

Not been to either but
