Chris, you've received excellent advice from so many, I hesitate to add just this thought. it sounds to me (from what you wrote) that the manager might be concerned that you've left a "free" spot in the middle of a work day. many managers want to ensure that "their people" aren't squandering tax dollars by doing nothing productive during trainings and meetings. perhaps if you can identify the purpose for this "free time" in a more productive context, the need to "fill" the time up with a key note speaker will go away.
best of luck!
