I can't see it as being a problem having two events either, as our Wedding isn't a Screening at all (we will be having children about and can't risk upsetting them with Reavers jumping out at them...) - we are looking more at a Costume Party with Auction and Raffles
Plus, I think there will probably be almost a month between both events, as the wedding will be the end of August, and I assume the SciFiFanSoc will hold the screening event towards the end of June
Two events in the same city can never be a bad thing though! The more we can raise, the better!
