Hmm, maybe there could be a way of letting the attendees know when certain programme items will be running late or being swapped around. A dry erase board at the main desk or something? Most times, we weren't sure what was going on at all (or couldn't actually hear the announcements over the mic) and we didn't really want to seek out and ask the staff, because you've all got enough work to get done. At the end of the day, though, I can totally understand and empathize with how stressful things are during the convention. I still can't wait for 2012.
