Looking for ideas for a mini road trip from Miami, ending up in Tampa.
2 brothers, 1 convertible Mustang (Hopefully its dry!), first class flights and 6 days and 5 nights.^

We will be arriving into MIA from CUN on the 7th January 2016 at 10am, and flying back to the UK from TPA at 9pm on the 12th January.

Looking for ideas of where to stop along the way on the drive up. (Ideally maximum of 2-3 hours drive each location).

Interests are:
Beaches
Outlet Shopping
Good Eating and Drinking (American, BBQ, Seafood)
Things we cant see here in the UK (Auto-sport? Everglades Airboat? Driving on the beach?)

So far, we only have Kennedy Space Center, Going to see Miami Heat? and South Beach on the list.

Thanks for all the suggestions!
