@sharonabe is right - they've already extended hours through December 9. Keep in mind that MK is the park that usually benefits most by extended hours - but your visit is during a stretch where there are 4 MVMCP nights. Although I expect they'll extend hours on December 11 (the only other non-party night at MK during your stay), you may not see much else when they announce new hours. If you look at the hours for the other three weeks, there currently is no difference in the hours before or after Dec 9 (which is consistent with past years).
