I was driving to Disney at the end of spring break when everyone else was driving north. The northbound traffic was horrible. It was backed up from Georgia thru North Carolina. At some points it was a dead stop. This was during the middle of the day. I would suggest driving at night to avoid delays if possible.
Driving from New York is out for me now. With the price of gas so high it just isn't worth it. When the gas goes back down to around $1.60

I'll drive again.
