cinmell - Everything runs everyday, starting on Thanksgiving or the day after Thanksgiving.
On days when the park is open late, the Christmas parade will run twice a day (Usually Friday, Saturday & Sundays).
The Fireworks may only be on Fridays & Saturdays during the first part of December so you might want to check disneyland.com before you leave.
The "Minnie Christmas show" & Carolers runs frequently throughout the day.
The cookie decorating runs from opening until dark. They have locations at the Fire Station on Mainstreet & the other is in New Orleans Square.
My family loves the Haunted Mansion decorated as "Nightmare Before Christmas", but if your family hasn't seen the movie, I recommend watching it before you go. The ride will make more sense and be more enjoyable if you do.
Also, make sure you see the "Small World" ride at night. It's decorated with thousands of Christmas lights and is beautifual at night.
Hope you have fun and we will be there too. We have AP's and go frequently during the Holidays!
