Thanks for all your help so far, we are getting further along and have found some nice campsites, no booking yet but we are getting there.
Our next issue is the tents, I like all your suggestions and could happily spend lots on them but due to his previous mountain experience DH wants something like this . I think we need to settle it by going to a camping show, I've seen you all mention them on here, but where are they? How do you find them? We are just south of London. Any suggestions?
