Roadtrip north/south east USA: New York --> Miami, May 2015: Which route?

[The Driving Dutchman]

First of all: Thanks Boothimd, AZBuck and Donna!

I realize the info i gave is pretty limited and that there are a lot of ways we could travel down to Miami.

In the latest chat i've had with the gf, she mentioned that she'd love to visit the places with a "southern feel" (she means Louisiana and in particular New Orleans)

So combining our love for nature/scenery, coastal routes (and ending with a fair amount of high temp days for the semi-cold blooded gf) i've come up with a different trip.

I'd really like opinions on this one as it crosses through the Appalachians and connects with New Orleans and follows the coast down and into Florida.

Please take note that this is just a google maps route with a couple of waypoints and a slight "drag'n drop" so any info or places to see along this route or places NOT to see is really appreciated!
