Taking place in Dallas/Forth Worth, tickets are already on sale. It's currently $85 for the weekend ticket. Prices will go up as it gets closer to the event.
The event will be taking place at Sheraton Fort Worth hotel. Event rates are $114 per night. Economy flights can be found at nearly half off with the coupon code on MACNA 2012 wbsite.
I found a 2-way flight from Columbus to Dallas for $476.
