Saturday is better, but don't cut your vacation short just because it is a busy travel day. We have traveled on that Sunday and if you allow extra time to get to the airport and for security you should be fine. Airfare is sky high that day ( pun intended)
Sorry I have to ask. And the Friday after Thanksgiving! My flight leaves at 7:35 pm coming home. So I know I have to be at the airport by 5:30. Hoping I don't have to leave Disney till 4 or 4:30.
