I'd almost recommend just getting room service. I'm not sure what time the first seating is, but it might not be until 7:30. Yes, you could eat that fast, especially if you let the CMs know you're trying to make a plane. My big question is, are you staying at the Grand Floridian? If not, I wouldn't even try. Another thought, though less magical, on your way in, take a look at the dining options in the airport. You could have more time to grab breakfast at the airport than if you try to rush at the hotel. Or, you could just hire a limo, or corporate sedan to get you to the airport and be on your own schedule.
