I'd avoid hotel hopping if I were you, it takes time to load/unload the car and pack/unpack. Suggest staying at 3 different hotels, if possible (one in Tampa, one in Key West, one somewhere in Miami Beach/Ft Lauderdale area).
I have a similar plan, minus Tampa. By the way, is Dry Tortugas NP worth the trip?
