DHS closes early on 12/15

The crowd calendar changed a bit for the week we’re going (12/15-12/21) and our original day for DHS is now a CL9. We’re thinking about switching to 12/15 which is a CL6, but the park closes at 6. Why does it close so early and does that mean we’ll miss Fantasmic and Star Wars Spectacular?

Should we do it anyway and try to hop back a different night for those two shows?

Probably a private or CM event.

Perhaps DHS is having another special event. like they did 12/16/17. That one was for Star Wars: Galactic Nights. The park closed early for a hard-ticketed event, similar to a MK party night. I believe there was no Fantasmic! that night.

I can’t find anything about one on the internet. Curious about what it might be and how TP knows.
