If you have the need to communicate venue
locations for a complex event, take a peek at how they set up the
schedule under "News Portal" by clicking on the News button the bottom
banner (or left column). The site uses Google Calendar (a free product) to show the name of the event, speaker, time, location, and a provide Google Map, of course. It's really amazing how many mini-events are happening during the main event. And being able to provide an event schedule in "real time" has been essential for this convention.
