Re: winter caravan questions
You are limited to one autograph per person. You can either bring your own item, or use a sheet they provide (for free) wtih pictures of each of the celebs. Basically, after the talk and Q&A, they line everyone up and you file by a long table where all they are all sitting. At least at the one I went to last year, they were also very good about posing for a picture or two.
