Hey there jay.
I normally play up at Ultimate Wargames in Fawkham but ventured down to the Ace Combat site near Brenchley. It is fairly open gameplay for a woodland site with loads of structures. Everyone there was incredibly friendly - in fact my gun packed it in that day but one of the regulars leant me one of his guns to use so the trip wasn't wasted. All in all the guys down there were very welcoming and they have a good set up there. I would recommend it!
Also check out UW at Fawkham if you're ever down that way!
