If you can take an extra day , the Kennedy Space Center is worth a visit. Its about a 3 hour drive North on I-9?(something). It was an awesome and humbling experience for this helicopter pilot.
You could also take in a Florida Panthers game at the Staples Center in Ft. Lauderdale, its about 1:20 South on the same I-9?. That should use up any spare cash.
There are tons of restaurants around the place. As the Auditor says, the 398(I think) Bomber group restaurant is a neat place to have lunch.
