Going to Disneyland the first week in December on the advice of our AP holder/travel agent friend. Glad to hear that his advice is substantive!
I remember going to Disneyland in late January just after they close HMH for refurb, the park was open late and seemed reasonably barren. I guess no one has money or time after the holidays... One of my favorite Disneyland memories was on this trip too, getting off Splash Mountain as the last ride of the night and walking back to the main gate with a fog/mist descended on New Orleans Square. Reminded me of how magical the place was.
