Every year after Thanksgiving, Disneyland changes into its Christmas theme. Christmas songs, lights, gifts, and anything else Christmas.
In Downtown Disney, you'll notice the change too. I was here last year and it was spectacular! On a cold night, bring a friend/date there to eat or drink! The trees are beautifully decorated and in certain areas, it makes you feel like you're in a dream. This picture of the trees doesn't do it any justice though. Regardless of the matter, you should still consider this place if you're looking for a romantic date place.
