Unfortunately I suspected there was some sort of illusion that popped out of no where because as we were in line I could hear people screaming (a startled scream) just before entering the unloading area!
I screamed anyway (mostly to further the spooks for the kids). Honestly, I think they were more scared by the idea they'd be scared, not because they actually were!
We enjoyed it and would certainly love to see more holiday overlays on the rides in the years to come (and judging by the crazy crowds at Disneyland right now... I'm not the only one!)
If you want to catch all if the Halloween theming... Be fast! November 2 it all goes away to make room for the Christmas theming!!!
