Help for British Buc fan coming to the Atlanta game.

Hi guys, not sure this is posted in the right place but hoping someone can give me some advise please.
I have a ticket to the Thursday night BUCS/Falcons game and I will be coming from Orlando as we are on a family holiday in Disney.
Just wondering what time you would recommend leaving Disney on the Thursday to get there in plenty of time. I will be on my own as nobody else in my party of 22 is into American Football so I don't want too long hanging around before the game.
Thanks
