Cheers Rich thanks for the welcome and all the info, let me check it all out although straight away I know I’m not around that weekend as we’re down in Walthamstow for friends wedding, pathetic excuse I know!
My mate has a similar problem. Didn't realise his wedding clashed with the GMU until after he'd booked and paid for the trip to Wales. Now he's stuck looking for someone to help him get out of the hole. He says he'd be eternally grateful for whoever can take over from him - 2pm Saturday 15th in Bedford. He says she's a cracking cook.
