Ft Lauderdale is 4 hours, away if you don't stop. Closer to 5 if you make pit stops and grab a snack.
For a 4 day visit, a car will allow to see more of TV, than a golf cart, (about 100 miles of golf cart paths).. TV is about 40 sq miles, which I think is a lot bigger, than most people imagine.
Enjoy yourself and don't get stressed out about seeing and doing everything, because you probably won't.
You will love it here!!!....... but then, I am biased.
