I like a lot of other people am a member of both. We use the CC to book ferries and get 7 Camping Cheques at the same time which comparing it with the Camping Cheque site we get the cheques virtually free. If we are using a club site you have the bonus of age concession if aged over 50 ( I think that is the age). I read the CC magazine online so get membership slightly cheaper. We have used both CLs and CSs and have found good and basic both. I insure my Caravan through the CC. It really depends on what you will be using the Club for as to which one to choose, a lot of people join both and see which suit them best.
As Carper says, some of the Forum members are in both Clubs. There are pros and cons for them both. My reason for being in both is that it gives a better spread of sites, especially in Scotland where, currently, the Caravan Club seems to be a bit thin on the ground.
It also gives some choice if you wish to visit a particular area and cannot get into one Club site, there is always the possibility of getting into the other. There is little to choose when it comes to the facilities offered by both the main sites and the 5-van sites. The "over 50s" concession is a good idea, especially for those of us who are fortunate enough to be retired and can go mid week thus leaving the weekends free for those who can only get away at weekends.
When first we started caravanning we were members of the Camping and Caravanning Club but had a very bad experience on one of their sites and gave up membership for a few years and joined the Caravan Club.
Join both for a year and see which suits you best.
Thank you for your opinions. I also am a member of both organisations for a similar reason as Dickers, that of the spread of sites throughout the country. I also agree that the 5 van sites available via both organisations are of a similar standard and price structure. The C&CC have confused the issue with their variable pricing structure last year but against this there is the site fee reductions for older caravanners. The CC does not have this concession but have a number of good private sites (affiliated sites) available to view via their handbook. Those appear to be more expensive than the proper CC sites but tend to be in more scenic areas. I have an opinion that overall the C&CC wins on the value for money question but could easily be persuaded otherwise depending on facts provided by the members on the forum.
