Last day for Haunted Mansion Holiday overlay?

[alohamom]

Does any one know if the official last day of the Haunted Mansion Holiday overlay (Nightmare Before Christmas)?
I think I saw somewhere Jan 6th and then another source said mid-January but I am wondering if anyone knows for sure?
Is it going longer this year?

I think it will be Jan 6th as usually it switches back right after Christmas ends. It was later last year because they switched Small Works first because Mansion was going down for an extended time for the queue redo.
