I went for the first time last year . It was amazing - we loved it ( was our first proper festival ) . We would have defo gone this year again , but are on holiday when it s on. Gutted we can t go - boo. Going to try to find something similar.
Anyway with the camping - we got there Thurs about 3pm and the place was FULL of tents thousands of them , everywhere , on hills, next to bins , next to loos , big metal fencing all round. I was not prepared for this as hadn't been to a festival before ( you prob have ).
The walk from the car park ( on a hill ) to the car was awful . We hired a cart when we got there , but the effort to pull a cart with camping stuff in up and down hills was nearly too much to handle ! We took far too much stuff like stoves , table , chairs, a suitcase ! Next time I would take bare minimum - just tent and sleeping stuff. I'd buy all my meals there , and just take a load of booze and snacks for the tent.
I wasn't prepared for ' no washing up 'facilities ' there is literally a cold water tap with a huge queue for it. I also thought it would be easy to get a shower - I was wrong . They give u a ticket and you wait ( took me about 90 min to get in. Shower was great tho . Some friends we met bought a sauna pass for about £20 quid each (a tippee tent full of steamy heat ) there are cold hose showers there . I never went in but it was seemingly a very liberal place with men , ladies & children freely naked. I would try it next time I think just to get a wash on a morning , but take some bikini bottoms 
If we went this year I was going to def book the camping plus . Mainly as you get your own plot so if you are any later than Thurs mid afternoon you won t panic about where you will be and the trek to the car and back with your gear !!! Plus there is a shower block just for the people in that area, & toilets.
Defo take a potty for your tent - the queues for the toilets were sometimes huge , and it was just easier to pee on the potty sometimes !!!! ( yes for me and the kids ) .
We had a night in Bournemouth the day after ( on Mon night ) it was fab , beach was gorgeous .You don t realise u are near the sea when you are at the actual festival. If I went I would do this again without doubt it recharged the batteries before long drive home. If u want hotel rec - let me know .
Enjoy
I ll be back in 2013 - it was fab. I could talk about it all day x
