Southern destination w kids week of New years? Where to go?

Florida is NUTS in the winter months. Your issue is entertaining the kids. We enjoy the Gulf Coast, LA, MS, AL and there are many nice parks to choose from. All depends on what you are looking for. Now Mobile area is close to Pensacola that has the Naval Air Museum and Mobile has the battleship Alabama you can go through, lots of things to see and do around New Orleans although I would keep away from Bourbon Street with the kids. I wouldn't think you would need reservations there as much as in FL.
