It's been a long time since I went to KBB's Halloween Haunt, but I was very impressed and thus it got my vote. I've yet to make BGT's Howl-O-Scream. Don't know if it's become a drunkfest too. If not, it looks like it could be good.
There's a perfect might of fun and fright. Disney simply don't to 'fright' well and aim their event more towards a younger demographic. That's probably the reason I'm not a fan of what the Mouse offers, it's simply not aimed towards me.
Notice that I didn't ask for people's opinions on the best event, anywhere. Just on which of the hard-ticket events they were most looking forward to seeing. I wanted to see which of the hard-ticket events has the most "brand name" value in the market - which one really drives people to pay extra, beyond an AP or a regular day ticket. (Okay, I'm giving away a future topic here.)
Hope that clarifies things.
Additionally, my local park, Worlds of Fun, puts on a great show at their annual Halloween Haunt event. It is not an event for the whole family by any means, but it is the only time of the year the park has that immersive, I'm not in Missouri anymore type of feeling.
I picked Mickey's Not So Scary Haloween Party. I like being at Magic Kingdom at 12
Oh, and for why I chose HHN, it all boils down to atmosphere. I've been to other theme-park haunts, but they can't even come close to Universal in that regard.
Even if you've never been to a Halloween event, if you have any interest in one, pick the one that most grabs your interest, based on what you've read or heard.
Me and the kids do LOVE holloween stuff at theme parks (we also do our own haunted house walkthrough at our home).
I would love to get to Ohio and do Cedar Point and Kings Island's walkthroughs, but since they are only on weekends and there are only so many weekends it's hard to figure out a plan for it.
We will do BGE and KD's stuff at least twice each (BGE we usually do for an entire weekend -- KD we usually start on their opening Friday night, but for some reason this year they aren't doing an opening Friday night, they are starting on a saturday).
We also will hit Dorney park, because it fits with a Hershey Park event we do each year in early October (before HP's holloween stuff though).
With KD getting multiple new walkthroughs this year, I think we will be satisfied.
