in Florida cons it's everywhere. Or at least was everyhwhere while WoW was mega-big. They'd have specific costuming contest for WoW only related costumes. You could always find panels specifically about WoW. The dealers rooms have lots of WoW related products. Guild RL meetups would take place all the time. Plus these were cons with a specific focus on anime.

Metrocon in Tampa an AFO are the two bigger ones that come to mind that I normally attend
