The biggest thing which trips me up is perspective and space. I'm uncomfortable in unfamiliar spaces and rooms, and unfamiliar perspectives within a room. This reduces my ability to perform, interact, and speak to people I don't know.
I'd suggest finding an empty stage somewhere and standing on it for 5 minutes. Just get comfortable. Get bored on stage. Try this a few times in different places with different lighting and furniture.
When you get to the conference, try to sneak onstage for 5 seconds, or even just peek through the curtain. Then visualize the space and try to become comfortable with it.
And try to channel your nervous energy into positive thinking.
