See this link , part of what Sir WC sent you. Five people have reported and given the site 9 out of 10. Pretty good I'd say.
I haven't been on it but from I've read I'd give it a go.

I know seen them and I've looked at the reviews on ccc there good as well. Think its me just panicking because it's our first holiday in the caravan in about a year. I'm fussy about CL , cls etc cos of bad experiences lol.
