Hi,
We'll be there too, W reg white ATF.
Follow the blue route signs to the camping fields. Word of advise, last year being a fool we followed the signs but couldn't see any blue, there was red, yellow, green etc. Turns out we were going the wrong way !!!
Remember not to take anything made of glass, they do ask and check for that when you arrive.
Be good to see some people there, hoping for good weather for a change too.
Regarding where the campervans park, look at that map bottom right hand side. Feilds E12-E14 are the camperfields by the blue route.
