The best place to keep checking is the official site or DLP magic. They post the opening hours in advance of the parade schedules so it may be up soon if not already.
At a guess I would say probably 10-7 or posibly til 8
The hours were 10-6pm in November (2nd week) last year when we went.
The park opening hours are up on the official Disney site to the end of October, so I shouldn't think it will be too long before the November hours are posted.
I think if you were to phone them, then you would probably be able to get hold of the opening hours. They were able to give me the hours for January, even though I haven't seen them published yet, so I would assume they know the hours for November too.
Why they don't publish them all online as soon as they know them I don't know, but oh well
