Probably not much. We had trouble getting groceries on Christmas Eve because everything closed so early. You might check for a Walmart. That's probably your best bet.
If anyone else is looking for the same info, I found Albertsons are open until 4pm and Winn Dixie until 3pm. We get in at 2:30 so I hope we can make it in time to pick up supplies for the 2 week stay.
Every Wal-Mart I've seen down here has been closed on Christmas day. As mentioned, Winn Dixie has been open limited hours the past few years. Otherwise, looking at 7-11 or maybe one of the 24-hour Walgreens.
