I'm worried I've misunderstood the instructions for resident tickets and made a big (and expensive) mistake. I'm an NP8 resident and live just down the road from Glanusk Estate, so I bought myself a resident ticket for Sunday, no problems there. But then my brother and his wife who will be visiting that weekend said they'd like to come too, so I bought another 2 tickets. Can they use the tickets and enter with me, or will there be a problem because they don't have photo ID with an NP8 address? Please help! I can't find a contact number to call. I can't cope with losing £110 if they can't use their tickets!!!!
