Ik don't no of its open in December.. I was there in oktober in the afternoon and it was already getting dark there.
It's not that far off the main highway.. like one block. It's worth going over there and seeing if it's open because if you've got flash you can still get great pictures!
Stopped by in November and it was drop box pay and self guided drive through for small narrow cars. Gift shop was closed. Assuming it'll be like this until tourist season.
Not 100% sure if it's open during December, nor have I been after sundown. I can say that it's a quick attraction (15 minutes) with a cool photo op and thats about it.
