Experienced speakers want to be successful, and they're not afraid to state their requirements. There are very few ideal rooms or room arrangements. Hotels seem to enjoy using long, narrow rooms with center aisles and poor lighting. Many times the back half of an audience is so far away, it's impossible for a speaker to establish rapport. Many rooms are poorly lit so the speaker is lost or the lights must be turned down in order to see the visuals, so the relationship between speaker and audience is nonexistent.
Every speaker deserves a proper introduction.
This creates an atmosphere in which you can be successful. However, few speakers enjoy the luxury of an acceptable introduction, even after providing one that can be used for the occasion. Introducers are often fearful of making presentations. The final element in setting the stage properly is never apologize. I only wish I would have had more time to prepare.
