Not such a great idea: Power outages

I was sorry to hear today that ASAE and the Center's Great Ideas Conference is having some power issues. According to reports (here, here, and here—thanks, Ben, for the updates!), an electrical fire is wreaking havok with both guest rooms and meeting space. It sounds like a planner's nightmare, but at least this first-hand report says they dealt with it admirably:

The ASAE staff has been extraordinary in helping attendees find their meeting rooms and making sure the show goes on. They have proven their mettle through this difficult ordeal which was far beyond their control.

Do you know what you'd do if something similar happened at your meeting?
