I would love to attend this year has I have never been before and have heard so much about it. I wish to camp from the Thursday night ,

Now can I just turn up and pay for me pitch etc or do I have to book?
Where is the nearest station to the campsite.
I camp and travel light so are there shops nearby.
More importantly is there a Off license nearby.
I also like to cook me own food ever on a couple of stobes or on the embers a Fire would the latter be possible?
Kind regards Pierre.
