Don't forget the time change too. Last time I drove(from about 30 miles northeast of Mobile), it took me 9 hrs including time change. I know this sounds crazy, but we fly! Driving down is not too bad but driving back after a commando week at the World was miserable!(Plus I was sad to leave.) A word of caution, for some reason they are ALWAYS working on the interstate around Pensacola. Sometimes traffic tie-ups there will add A LOT of time to your trip. Hope you have a wonderful time!!!
