We've used Camping Cheques since they started - and now can go twice a year (May/June and August/September). If you want to find out how much you'll save, do this by looking at the prices quoted on the website of the site you fancy, and then comparing that with the cost of the Camping Cheque. Just as a 'for instance' Camping Val de Cantobre at Nant, near Millau, takes CCs (CC cost 14 euros for pitch/two people/car/caravan/tent or motorhome, awning, electricity) - site website quotes 20 euros 50 for the same pitch (that's a nightly saving of 6 euros). Ranc D'Avaine in the Ardeche (again CC cost 14 euros, site website quotes 25 euros 75, saving 11.75 euros per night). There are some sites with even bigger savings! Some sites even offer 7 nights for a payment of 6 cheques, or 14 nights for 11 cheques. There's really no drawback, and any cheques you don't use this year you can carry forward to next year! We also take an ACSI card, and stay at other sites as well - but nearly always make a Camping Cheque site our main base for the biggest part of the holiday.
