Christmas at Disneyland
I love how the Disney parks and resorts do holidays, especially Christmas (there's a reason we got married at WDW in December). Disneyland and California Adventure are certainly no exception, although the Christmas decor was tuned down due to the Diamond Celebration, you could still get into the holiday spirit.
My personal favorite was the Haunted Mansion overlay with the Nightmare Before Christmas (we never made it onto It's A Small World to see it's Christmas overlay)
Up next: the FOOD!
