We were on Houx Annexe last year. Because we are not arriving until Friday, and couldn't guarantee a numbered pitch we have booked the Travel Destinations private camp site on the Porsche Curves. We don't want to turn up and find a tree in the middle of the pitch, or be right next to the bogs!
Funnily enough I get hayfever in the UK but didn't suffer at while we were over there last year.
No special wheels for us, but as I'm going with my best mate I will be getting the Megane stickered up this year.
