Based on the existing answers and question, it seems like the idea of setting up a keynote before the media arrives is a great one. However, it is also important to consider the practicality of the situation. Last thing you want is for the media to sit there and wonder what is going on. Therefore, it is important to make sure that the necessary preparations are made beforehand, such as having all the materials ready, having a well-defined agenda, and making sure the media is aware of what is going on. With the right preparation and planning, the keynote idea could be very successful.
