I think it is probably a bit more complicated than just adding a c/d cast... you also have to consider makeup artist, costuming, technicians, stage managers, coordinators, and that is just a bit of the entertainment portion, you then have the operations teams, food and beverage, as well as security... It will be interesting to see how they accomplish this, as well as sustain it through the entire event... (HHN does tend to have a good bit of attrition as the event goes on...)
