Am travelling through Spain and France using Aires where possible but campsites sometimes. I normally use Camping Cheques but this year have been shocked at how much discount can be had by offering cash instead. We had the need to spend 7 nights on a site and they did it 26 euros cheaper. Another site was offering 15 nights with a 70 euro discount for cash. Makes the Camping Cheque and ACSI appear a rip off. We have always received an exchange rate of at least 1.41 which makes a £14.95 cost over 20 euros. We have used Camping Cheques for over 15 years now but it's really not worth it now as they appear to be keeping there prices high. Don't be frightened to ask you've nothing to lose but a saving to be made.
