Additionally, Domaine de Gaujac (not in this list, but which accepts Camping Cheques from 20th August), will include under 13's in with the Camping Cheque - so no child supplements! There are also several other potential overnight sites taking Camping Cheques from 18th August - Bois de Bardelet, Lac de Panthier, Le Bontemps - so it's possible for a family to take a two week car and caravan holiday down in the south of France, for £290.20. This includes two overnight sites in each direction, a ferry going out on the 18th August with DFDS, at 8.00 am, returning Sunday 2nd September at 10.00 am (last night at Gandspette with Camping Cheque), two adults, three children, and fourteen Camping Cheques which pay for all the campsite nights, as Domaine de Gaujac does 7 nights for 6, meaning that you only need fourteen for a fifteen night holiday!
