Thank you Steve and I'm sorry to have repeated a question that had already been discussed. I'll probably have a lot more questions soon and will try to check first, using the search facility, although often one isn't sure what words to use and so doesn't find it. (If there's a problem, I think the campsite owner will help, as he and his family are quite prominent in business here, so they should have some influence, and they're a very nice family, too.)
