Hartford and Orlando are about 1,037 miles apart by road. Split the difference and you arrive near Raleigh, the city closest to the halfway point between them. That splits the trip almost evenly — about 10 hr 59 min from Hartford and 11 hr 1 min from Orlando.
Over this distance most people will fly rather than drive the whole way. Raleigh still makes a fair, central place for Hartford and Orlando to converge, splitting the travel instead of asking one side to cross the country.
If Raleigh doesn't have what you're after, Richmond and Charlotte are also close to the midpoint and worth a look — each keeps the drive reasonably balanced between Hartford and Orlando.
