You cant park by the tents so cars will have to be driven to the stand, then stuff carried over to the camping area.
A map of the layout has already been posted so you could use that as a guide, but last year we were told on entrance where to go e.g. third turning on the left, keep going and your on the right etc. Its just one huge open field with roads going all over it grid style, so its quite easy to get lost, especially when its busy! imo.
