Disneyland doesn't have the Mickey's party, but they do have:
* Dress up the parks - Disneyland in traditional Christmas colors & DCA in golden colors
* Dickens carolers on Main Street
* Christmas lighting ceremony each day at dusk
* Holiday themed fireworks
* Snow after the fireworks
* Fab 5 characters in Christmas costumes
* It's a Small World Holiday - the whole facade is decorated, plus the ride has a Christmas theme
* Haunted Mansion - Nightmare Before Christmas
* Decorating cookies at Main Street & New Orleans
* Christmas treats at the French Market restaurant in New Orleans
* Christmas Parade beginning on Thanksgiving Day
* Santa on Main Street
* Santas Beach Party at DCA
* CL Processional is usually first or second weekend in December, and will probably be on 12/10-11 ... maybe on Main Street - in front of the Train Station, facing Town Square
