Hi and thanks for the replies. I think the Expo is actually just what I need - I have lots of questions so having everyone I need all in one place would be pretty handy. Might leave the kids at home though - doesn't sound like their thing and I can't imagine trying to entertain them in queues all day! I found a link to the London expo in a couple of weeks just incase anyone else is keen.
