i have done both we drove to florida twice and may i say NEVER NEVER AGAIN, forget it we use to drive down in the 1970's when there were'nt half as many cars on the road and this is how we would do it, my husband would drive from ct to rockkky mount NC which is the halfway point 12 hours and then i had to drive till we got over the florida boarder then he would drive again, that took 24 hours eating at mcdonalds on the way you have to time it just right so you dont get stuck in ny traffic, i think we left at 4am, then we get to our hotel and waste one whole day sleeping!!!!! it always took about 3 days to recover from ddriving, and we were both in our 20's then, now i would'nt do anything but fly, airfares are cheap enough from ct, then rent a car from national car rental right at the airport and trust me you save yourself a lot of aggrevation that way, also if your car breaks down while you have a rental they bring you another one if you have your own your responsible to fix your own, oh yes and if you drive lets not forget about those annoying south of the boarder billboards that start about 500 miles so it seems before you get to the nc/sc biarder, and if you leave at 4 am you should get there about 2 am when its closed anyway.
