I'm really disappointed with it this year. I was a part of the thread on their forum regarding how long they were taking to annouce guests and how that becomes difficult for those of us not local to make a choice to book train tickets on a whim without knowing the calibur of guests etc.
So yeah, still not enough to lure me and if they do manage to pull it out of the hat, far too late for me now cause of trains. It's a shame as I loved going to last years. Hoping to save for the London one in May now and if the same happens i.e slow release of guests, I'll just have to settle with our local Manchester one in July. *sigh*
