we are thinking of visiting right after Christmas and staying for New Years...I imagine it may be busy...but other than that is there anything cool gooing on that time of year?
On NYE, they shoot off fireworks twice. Once(briefly) at 9:00pm for WDW and the east coast and again at midnight for the west coast. It is insanely crowded(but my family did DCA and found the place nearly empty). It's worth doing at least once.
