I just registered here to help some folks out. I just got my reservation for Halloween day and got it fine. We had to redial 832 times and when I finally got through on the 4240 number I was hold for roughly 2 hours. The lady told me that Halloween day isn't sold out yet but they're having trouble with the inventory repopulating and they've never seen demand like this for anything so they're a bit overwhelmed. She said free dining, Christmas, Not So Scary party, etc... pale in comparison to the demand and that's why no one can get through. I'm personally just too damn stubborn to give up. When I read it was sold out on here I was a little dejected but I tried anyway. Good luck to you all and don't give up, just hold them on the phone until the inventory repopulates for your day. I'm assuming that like most call centers they can't just hang up on you if you have valid questions and all.
