Take basic stuff, like drinking water, with you. The amenities amount to three Portaloos that stink. End of. No tap, even. This is compensated by the fact that 500 yards from the gate is a proper choice of food/supplies, Chinese x2, Pizza x2, Curry House x2, Chip Shop, Co-op Mini Mart, hairdresser( ).
Also, be prepared for mud. The whole site is low lying and marshy with mozzies for breakfast, lunch and dinner.
The upside is that the fish are in perfect condition and of good size.
Don't even think of breaking the rules, by the way. The bailiffs are on the case, at all times.
Please let us know your thoughts when you've fished there. I wish you good fortune!
