As far as today specifically goes, it looks like they have movies scheduled to start at 10am.
My experience has been they open the doors about 30min before the earliest showing. I like early matinees and have only had once experience where they didn't, but overheard a comment between staff about being short staffed that day which I assumed was why.
Unfortunately, I'm not sure. It isn't posted on their website. Someone may have to call and/or visit them in person and ask them. It should be posted by the cashiers.
