That’s not a Sunday Brunch. It’s not even a brunch. And neither is Chef Mickey’s. Those are just breakfast buffets, and 'Ohana isn’t even really that.
A brunch serves both breakfast and lunch dishes at the same time. Also they usually have an omelet station and a carving station.
Other than HoB, none of the Disney resorts or restaurants do Sunday Brunch.
The closest you’ll ever come is to book the latest reservation for Crystal Palace at breakfast (10:30) and dawdle until they finish changing over to lunch at about 11:15.
I am not sure about the non Disney hotels, though Dolphin used to do a Sunday Brunch.
And Shoney’s is just a breakfast buffet.
