probably no more than 10 minutes depending on traffic...it's really easy to find and everyone around Disney can get you to I-Drive if ya ask. Very touristy part of Orlando...there's a lot more stuff down there to down if you want. A goggle search for International Drive should give you some good info.
Another option since the game is on national television...there is a Buffalo Wild Wings in the Crossroads Shopping Center near Downtown Disney. That should have the game as well...shouldnt have a problem finding that either if you ask. A little closer to where you will be and probably wont be as crowded.
