If I'm by myself, I'll fly but usually i'm not so I drive. It's about 8.5 hours from Durham, NC. I also tend to make stops along the way in the Daytona area to see friends I made living in FL so I like the flexibility.
It's so much cheaper to drive. I just got back from Daytona last week. It cost me $165 in gas round trip. Flying 2 people and a 2 day rental would have cost double that at a minimum.
