if you're into Bird photography, when you zip past Ft Myers in Florida, you could pop over to Ding Darling on Sanibel Island (best early morning) [take exit 131 on I-75]
and of course, on the way across Florida, you can do one of the air boat rides and see some gators in the Everglades (bring some mosquito repellent though!).
Miami is also fun of course
