Considering that
Disney+ Day would have been yesterday (9/8), it seems to have gone unnoticed this year. I think the promo was less about selling cruises but about bolstering subscription numbers for Disney+. They still struggle, but it seems they are trying new things to help Disney+, do my guess is that we won’t see a return of that promo.
Of course none of us has any true insight on what they do and think!
