Car situation...
When I was there for my CP, me and my best friend each didn't have a car and we did just fine. It wasn't that bad getting to and from work, and I enjoyed the time on the bus to read and relax and just sort of mentally prepare for my workday, read, or listen to my ipod. I liked it because I was always on time. As for grocery shopping and things, we didn't have a lot of trouble hitching a ride with a roommate who could drive, and getting to and from the parks sometimes it was easier because we could just catch a bus and go, instead of dealing with parking and things.
I did get a car for my professional internship and I moved out of housing (...except then I worked in housing, so I was in and out). The driving in Florida isn't bad at all. I am a nervous driver and I'm from Maine which is VERY chill, and I was worried about Florida traffice and I4 and things, and it worked out just fine. I did have my car for a few weeks on my CP, ran into the same trouble with the insurance policy (what a pain in the butt), and I liked having the car to get to and from work, once you get into a good pattern of when to leave, where to park, etc.
I would say that honestly, without a car is just fine. With a car is just fine. It depends on how easy it is for you to bring your own car. If you have it, great. If you don't, no big deal.
