The level of interaction is very different since you don't have any face-to-face. Communication is a lot more difficult, the energy is different, and camaraderie is different. You're basically going to have to create a room of excitement on your own so it's a lot more output of energy from the facilitator. What we do with our clients is help them create interactivity every four minutes so that the instructor doesn't have to be "the energy" all by him or herself-the audience is creating the engagement for themselves.
