Holiday time planning for Universal Orlando

I know that UO is more chill and needs less planning, but I am not that type of person. Trying to create my spreadsheets for Dec 12-13th and I am not sure what shows times are. I have Macy’s parade for 5 pm, Mannheim Steamroller for 6 pm. I am not sure if those are true yet.

When will holiday events with times be announced? I want to add Grinchmas to my schedule. I don’t know what other holiday offerings there are.

I am an AP holder, so I have been many times, but not for the holidays.
