I don't think so, sadly. I believe the last day for the Halloween party is November 1st, and I think the Christmas party starts up the 15th of November, but I may be wrong. It's extremely unlikely the lights will be on the castle(As far is I know- then again, I could be wrong!).
We will literally just miss it! Bummer. The last MNSSHP is on Halloween this year, because I had hoped there would be one on 11/1 and there isn't. Oh well, now we have a goal for the next time we go!
