I’m positive that’s not for HHN. First, from the tweet thread and the sunlight, I think that’s soundstage 19, which hasn’t been a house location in years (poster says it’s “closest to bur behind BMG”; SS 22 has breeze ways all the way around it, so it can’t get direct sunlight and 22 wasn’t used this year either). Even if it was a HHN soundstage, they wouldn’t be doing new construction in December. The parks rent the sound stages from production for HHN, which is why they construct those over the summer, and you can tell the image is new construction because it hasn’t been painted black.
