To best answer your questions, we would need to know your destination in Florida and also the number of days you plan to be on the road.
Here are some of the places I would stop when on a road trip to Florida when driving on I-95:Philadelphia
- the City of Brotherly Love to explore Independence Hall and eat the famous Philly cheesesteakWashington, DC
- get to know our nation's capital. Visit the Smithsonian museums (they are free) and iconic buildings. I suggest getting a reservation in advance to visit the U.S. Capitol. Here's the info: https://www.visitthecapitol.gov/plan-visit/book-tour-capitolColumbia
SC - plenty of free indoor and outdoor activities. Check this out: https://www.experiencecolumbiasc.com/things-to-do/free-things-to-do/Savannah
