If you want a bit of scenery, at around St Augustine, Fl go over to A1A on the coast and take that the rest of the way into Daytona.
It's much slower than traveling the interstate, but you get a good view of the ocean and some cute little towns along the way.
St Augustine itself is a nice place to visit, and they've got an area dedicated for RV parking near parking garage. On the map below the pointer is on the parking garage. The RV parking is to the west, at the other end of Francis Field, off Riberia Street.

Lunch (or dinner) at the Funky Pelican in Flager Beach is also recommended.
Good food, good view, good service, reasonable prices.
