Probability of 2nd Fantasmic on EMH night?

I’m looking at Dec 23 at HS. There are already evening EMH posted (until 10pm). Can I assume that there will be a second Fantasmic show? There is only the one at 8pm listed now. Trying to decide whether to do the Fantasmic dinner pkg for first show (ADR already made) or take my chances with stand by for a second show, if it’s added. We really don’t want to stand in line for an hour for stand by. I’m assuming even a second show may be quite crowded that night? Thanks for any help.
