I thought that the trip from Key West to Miami would be more over the open water, but as a midwesterner, I was super surprised at all the keys!
A personal fan of road trips, this was no different. If you have the chance, rent a convertible (we did), and soak in the sunshine as you travel.
A lot of the scenery is beautiful where you're literally crossing the ocean; however, along the highway it's kind of run down. (Think boarded up shops, seedy-looking bar/restaurants, and po-dunk gas stations).
We didn't really venture off the highway until our stopping point in Key Largo, so perhaps we missed some of the charming, waterfront places, but oh well. It gives us an excuse to do it all over again!
