I don't understand who's bright idea it was to plan an event where most costumes cause heat exhaustion in cold weather and decide, " hey Florida in august sounds perfect!" WTF?! Would love to go, but I'll pass... 
They have A/C in Florida!
it doesn't help if you have to walk from your hotel
Yeah, it also doesn't help if you want to do anything else while you're in town. There's no way I'd travel across the country to spend 4 days solely inside a convention center. There's soooo much to do in and around Orlando. I'd
have to go to MGM (or whatever they're calling it now) and see my previous place of employment (if it's still there).

If it's got to be in Orlando, they ought to do it in October or March. The weather is fantabulous then, and crowds are nonexistent.
