We book through MRI every year 'cos I just can't be arsed to faff around with anything else. I must admit that one of the main advantages of their marquee is the very nice toilets for that essential early morning dump. Sheer bliss!
We get our saturday morning breakfast there as well but I've never heard of the bar being free - they always insist that I swap some Euros for the drinks they give me.
Their VIP area is a total rip-off, you must be mad if you fall for that one.
A couple of years ago there was an English couple running what sounded like a very nice, private campsite.
www.valan.co.uk (or .fr) I'll see if I can find their site.
