Dave: You asked "Does anyone know if I have to pre-book a caravan pitch at North Oxfordshire College, or can I just turn up on Friday ? A friend of ours is also interested in coming, will she be able to use the indoor camping, or again will she have to book first?"
I know Derek & Mary are up to their eyes, as I have just left them doing the lamination of signs, preparing photo copying and dealing with last minutes problems etc.
Anyway, I believe the answer to your question is Just turn up - first come first served!
See you Friday.
