We just returned a couple of days ago from our trip. Total mileage including a side trip over to The Villages ~2600 miles.
Southbound we took I95 all the way.
We left LI shortly after 10pm and hit our only traffic for the trip down at 10:30pm. The Belt Parkway is a mess with constuction. Avoid this at all costs. After this it was smooth sailing to Savannah.
The Baltimore tunnel at 2:50am

Quick stop at South of the Border around 11:00 am

Arrived in Savannah around 2pm
On the road the next day around 7:30am
A quick stop at the Florida welcome center around 9:00am for juice and DD to admire the local wildlife

Around Jacksonville 9:40am

Here's out exit 11:50am

A most welcome sight

And finally we pull in to the FW resort at exactly 12 noon

For the trip home we left from The Villages around 8:00am and took 95-26-77-81 with a stop at Natural Bridge, VA
Traffice was heavy on I26 but moving. The only stop and go traffic we hit was on I77 north of Charlotte. We hit this area around 5pm or so on the Fri for labor day weekend. It took about 45 minutes to go about 10 miles. Other than that we had no problems.
