camping at ultimate dubs

As post says. I am travelling down from the north east on Saturday afternoon but most of the bed and breakfasts have been booked or they have hiked the prices.
I want to travel down on the Saturday as I want to enjoy the day and don't want to be tired lol. Failing this my other option is to convoy down on Sunday.
Does anybody know of any good places I could pitch a tent. Near the show
Cheers
Dave
