Camping Club Europe

Does anyone have experience with this organization? For a small fee, they allow you access to a database of thousands of European campgrounds. There's no sample of how much information is provided (like cost, directions, facilities, phone numbers). Can anyone recommend a camping membership that is useful for camping travel in Europe? Also, having camped in the SW USA, I am aware of many places to camp for free. Are there such comparable areas that I should learn about? Like National Forests?

Before you camp anywhere in Europe (outside July and August) google these 2 and save yourself a LOT of money: these guides also give honest advice and include most of the best campsites. OK? The guides are ACSI and Camping Cheques. To sum them up it costs 14 euros a night to camp on any of the sites and this includes 2 people, car, tent/caravan/motorhome, electricity(outside July and August). All campsites are inspected anually. You get a very useful guide book in each case. ACSI has much more campsites but Camping Cheques gives you a nicer guide book. Un besito. Peter
