Agree w/ Cody - I think the fair response is that this is simply the way they have chosen to do things and is not a lack of understanding of demand, sales numbers and other factors (such as the existence of other conference centers and cities) - this is all data they are privy to that we the huddled masses aren't.
My hunch is that they simply don't want to commit staff and other resources for more than the event as it is currently laid out.
