During your time at the exhibition hall, did you see any trade shows that had more overall activity and interest among all their booths? I'm curious to know if there were things done by event organizers with theme or type of event that could help make a tradeshow be desired or enjoyable. Tradeshows about new tech for example, such as CES, typically are interesting for people to discover what new things are being developed.
