I hope you're staying in Florida for awhile
It would be a shame to drive there and not enjoy it a bit.
Welcome to the Roadtrip America forums.
One of our moderators did a trip and wrote a great report about it. If you scroll down to post #10 in this thread, you should start getting some interesting ideas of things to see and do. It's a good read.
Other posts that might have some useful information are here and here.
I'm sorry I'm not able to help out more. I've never driven much in that part of the country. But, hopefully, these will point you toward some ideas and somebody with more specific knowledge will pop in here to help you out some more.
Happy planning!
