MummyPig, I am DYING, literally dying of jealousy, re your site. 
We have an oldish caravan, sited in Dorset. Dh says it is too old to tow to France, Spain. Plus the driving for him, the tolls, the nightmare of getting there = just not possible.
So, we put up with british weather. In dorset. The site is fab. 2 miles from the road, and the kids run wild, they only back for their dinner !!
But, it has pissed it down on us so often, for the may bank holidays and week in august, that I begged dh for sun. Ibiza, Spain, anywhere.
The weather is getting so bad, it is killing the site in Dorset. People are cancelling left right and centre.
I don't know what to do.
But am hoping that our 10 days, in a couple of weeks time, remain 'fair', atleast. And does not piss it down.
One year, we came home early. And dh went back and shut up shop, on his own. It was THAT bad.
I don't know what you guys think about UK camping, but I think that the weather means that it is surely in decline and may struggle to survive.
