Disney officially added Main Street Electrical Parade and Wishes daily over Thanksgiving Week from November 22nd through November 28th. The Electrical Parade is currently scheduled at 8pm with Wishes following at 9pm. A second Electrical Parade will assuredly be added at 10pm daily, though we may not see that update until the middle of October.
I never heard a good reason for the original omission of the nighttime entertainment, though each is scheduled one hour earlier than expected. In past years, the Electrical Parade has been scheduled at 9pm with Wishes following at 10pm. I’m not sure why they would move the shows up an hour, which is a departure from what Disney has been doing to ease nighttime crowds, which is schedule the entertainment as late as possible so fewer people are around to see it. Anyway, expect the Electrical Parade at 8pm and 10pm with Wishes at 9pm during Thanksgiving Week.
