- December 25-31 - Animal Kingdom closing at 8 p.m.
- December 25-31 - Typhoon Lagoon will be closed and Blizzard Beach will be open 10 a.m.-5 p.m.
Also just for the sake of completeness, January, February and March hours at AK have been expanded to 7pm. To me that says that they are probably going to be extending the hours later in December, which is busier than those three months. Also I think it was missed that first week of november came with later closing times for HS so there is still a chance that they might expand hours (making the dessert party later than our worst case scenario) for early december. Crowds are probably about the same for early november vs. early december.
the November update is for the week BEFORE the christmas party kicks in. There is no party that week at all, it is the lull between halloween and christmas. So hoping that the next update goes clear through the end of december. MAYBE!? probably end just after thanksgiving dammit.
