It's the second panel up of a run of extremely popular panels - I'd be looking at sitting through 'ParaNorman' and settling in for the day. If you're not that bothered about getting in the front half, I'd be thinking from 8am onwards; if you want to see this stuff up close and personal, any time before 7am, even from midnight. Check past the tents the evening before, see if people are queuing. I'm in the hotel directly opposite and will be posting tweets on line updates, if and when I see them (@lennyukdeejay).
