While I am a WDW veteran, I am a Disneyland rookie. We have booked a stay over the Thanksgiving Holiday at the Grand Californian. We are contemplating changing our trip to the second week of Christmas Break (December 29 through January 6). While I know that crowds will probably be terrible at both times, is there one time that will be worse than the other. We are planning our park days to occur on January 2 through the January 5). Any thoughts would be appreciated.
