busz,
Since you've got a few months before you go, why not suss out your local flying clubs (if you haven't already) and find one where you feel comfortable to fly and hire from when you get back. I'd recommend that you then get at least some of the exams out of the way with them first; that way you reduce your workload in Florida and also start to build a relationship with the club you'll be flying with once you have your licence.
The exams aren't too bad, but there is a lot of studying to do to assimilate all the material and if you're on an intensive course anyway you may be glad of the chance to relax in the evenings rather than just go home and study.
Good luck anyway!
