John Boy, I do hope I am not going to alarm you too much before you go, but if you have not camped in this area before may I strongly suggest you take the following.
1. Some form of Barrier Tape.
2. A hosepipe.
The reason I say this, is because there used to be some bushes behind your pitches, which coupled to the fact they are against the concrete wall and partially hidden by the entrance buildings, meant they were all too easy for people to use as toilets. With any luck, you will be there early enough to discourage this from happening, but last year the people in that area did not arrive until friday and it was a bit pongy.
There is also a water stand just about in the pitch opposite to you, so if you take a flat roll-up hose and adapter you will be able to give it a hose down if required (also helps to get the dust off the cars
)
Just thought I should give you a heads up.
