Disneyland really doesn't do anything special for Halloween.
The past few years, they have converted the Haunted Mansion to a Nightmare Before Christmas theme at the beginning of October. And they've had some trick-or-treating in Downtown Disney on and around the 31st.
But, for the most part, Disneyland concedes Halloween to Knott's and other local amusement parks.
Disneyland celebrated Halloween for a couple of years back in '95/'96, but they just couldn't compete against Knotts Scary Farm, which is hugely successful. There are no Halloween parades or party like at Walt Disney World's Magic Kingdom.
Thanks!! I know that always can count with your help.But for now we just want to go to DL and REALLY enjoy the party or the little man win and go Universal Studios too (mom's love )
