Six Flags Discovery Kingdom

Check this out I just saw that the Six Flags in the San Francisco Bay area is doing a Holiday in the Park. There is more info on their website, but here is some information on this event that I got from their website:

Themed holiday wonderlands feature life-sized toys, non-stop entertainment and festively decorated areas to get everyone into the holiday spirit.
