One thing to look out for....
I helped my mate pitch at Home Farm last year, as his car was out of commission. After ages waiting on arrival, we were led to his pitch by a lad in a buggy. Pitch was empty, but on looking, all the mains points were in use. OK - chased after the lad, and he led us to another pitch. Same problem with no hook-up, however. In the end he left us to look for an empty pitch with hook-up. Make sure your pitch has hook-up, in case. Seemed to me like they were packing in more vans than the site could cope with - squeezing them in everywhere.
Very tight manoeuvering around - at one point, we had to move someone's windbreak, just to drive down the "road." Beware if someone's coming the other way!
Site very crowded and appeared noisy/wild.
