If Small World Holiday is reopened at the end of November, they might still have that open when you visit. Not sure about Haunted Mansion Holiday, that usually is the first to go down after the Holidays.
If your looking for decorations and not rides decorated, you may be in luck as you can't take all the decorations in the whole park down in one third shift. They will be dissapearing quickly however, and Holiday rides will go straight down.

by intoxication, i'm pretty sure the OP meant that disneyland just gave us a free acid trip.
