Thanks to Mike and his team of helpers for making this a really successful and smooth event. I echo the above statement....give Mike a break, about 18 hours wasn't too long to wait.
The noise was loud in the hall, and in my opinion no louder in the mezzanine than the main hall, but it was hot. Fans may cause more issues than they solve, due to the lack of space and counters and paperwork flying away!
Overall a great event with a lot of great people.
