YES! that's how to live 
Hang on! (x) of you, (y) of me, dont mind playing Airsoft, I make that Pimms O’clock
I was going to ask about 'facilities' but just checked on GZ web site and they offer this information:
Our site has plenty of flat and clean car-parking space, in an easy-to-access area. We have clean, on-site toilet facilities for both male and female players. We've also got fresh, running water.
Our hut is situated within the car park where you register to play, hire any equipment you want and the on-site shop can be found there as well, selling bb's, gas, mags, face protection & loads of cool kit.
We also offer snacks, drinks & hot food to keep your appetite at bay during the day. From Coke & Fanta, Pot Noodles, Crisps & Chocolate to Curry or Chilli with Rice, Sausage Hot Pot, Stew, and even Spag Bol.
Woah, hold on! There will be toilets and water, that I know. I don't know whether the shop will be open or not - not sure who runs that: i.e. GZ or Zero One. Will check and get back to you.
You've got nothing to ein, zwei, drei, vier
That would be most useful...
Apologies - I am used to being self-sufficient...! 
You've got nothing to ein, zwei, drei, vier
Heh, me too - but there are players who will be travelling very light though...
Still, good to know the most vital water is already on site and loos are a comfort!
