I'm checking this regularly as well! We are there from the 18th-22nd. I checked out the hours for MK in 2015 around the same dates, and it was open from like 8 am until 1 am almost every day the same week (7 am for EMH). Right now it's still saying 9 am-9 pm, or 8 am on EMH days. So I'm assuming it will change but I have no idea when that happens. Epcot currently says 9-9:30, and last year it was usually 9-10:30 so I'm not anticipating that to change much.
