It looks like you have to be a professional haunt or vendor, but there are ways to get on the lists. If you're lucky enough to know someone that can hook you up, you'll have contact HAAS (there is a toll free # at their site) for the pricing.
As far as the haunts that are going to be open, you can go (if you buy tickets in advance). I've attended a few here in Houston (not the actual convention, but the haunts that had a special night for the vendors will let you buy tickets even if you're not a pro). It looks like http://www.thedarkness.com/ will be having a special live actor run-through during the convention, but you must purchase the tickets in advance. I would call them and ask what you can do to go.

Thanks Frankie's girl...yeah, I do know the details about being invited or owning your own biz... but, there's no links for ticket pricing anywhere, I'm assuming probably $30-40 per day or can get 2 day pass or something.
There is NO cost to get into the tradeshow, once you are registered. You technically have to be a business entity to get registered, or get an invitation from a vendor. I've heard that Corey from Minions Web is happy to oblige. Just e-mail him and ask. I happen to have a tax ID#, so it's never been a problem.
If you have Halloween/Haunt related receipts totaling $200 or more you can register as a home haunter. There is no entry fee. The show is amazing and packed full of ideas for the home haunter. Bring cash and a credit card because there are some great deals there too. I hope to see you all there!
