Oh wow fog machines, too?!! I would sooo love that. I'm very into Halloween. I love decorating the house - we go all out. I have fog machines, haunted house music, tons of props...skeletons, ghosts, spiders, "flaming" cauldrons, chains, purple lights, spider webs, lighted candleabras...you name it! All the kids in the neighborhood (and adults!) look forward to it every year. We were on the local news one year when I was renting a house across town. I'm a little more low key now - but as I get money to purchase more stuff, it'll get better. LOL. Unfortunately, photos don't tend to come out very well ... I've tried to photograph stuff and they come out too dark.
Even with a flashlight I don't think DF would have a good time if it's dark. I also have a friend who has night blindness and she said compare it to closing your eyes and trying to walk. Yikes. I can't subject DF to that at Disney.

I hope there's lots of photos that some of the folks going post. I'm dying (pun intended?) to see how it looks!
Speaking of which, when does Disney put out decorations and stuff? During the hour they clear they park? Or will the park be decorated that way all day?
