On our recent 3 day sailing (Fri-Mon) from 10/14 - 10/17 there were no daytime showings of any of the evening shows that are normally done in the Walt Disney Theater. I know when they did Covid restarts they were doing that to allow for some more social distancing but in the last two cruises we have done - the Wish just now and the Fantasy this past summer, there were no daytime showings of the evening performances.
There are plenty of movies showing during the day but not of the 3 live shows on the Wish. Hope this helps.
