I was there yesterday for P!nk and had the most amazing time. It was my first time there but was with a friend who is a veteran 😀. We took picnic blankets and had early entry, so go quite a good spot and set them down. We left them until just before she came on, which meant we had our 'spot', so to speak.
I know it says no chairs, but we saw a couple of people with those foldable fishing chairs, and another person had what looked like a blow-up seat.
The toilets were really good, lots of them and what I would class as proper toilets in a really clean cubicle. None of those port-a-loo type things with blue water. Really decent hand washing facilities and proper air blowers instead of towels to dry your hands.
If you have an Amex card, take it with you as you get 5% off purchases and free water bottles (like the chillies bottles).
Food was really nice with plenty to choose from, and cans of coke were £2.80 each.
It took us an hour to get out of the park and to Oxford Street tube via a quick pit stop at McDonalds for a cuppa 😀. The concert finished at 10.25 and I walked through my door at 1.00 am.
I am doing it all again for Billy Joel on 9/7 😀
