Oh dear God....no 95!!! I made the drive from WDW to Pompano Beach, about 20 mins north of Ft Lauderdale. I took the FL Turnpike to Jupiter, then over to 95 and down to Pompano!!! It was probably the worst 45 mins of my life.....80-85 mph, bumper to bumper, in the RIGHT lane!!! It was horrifying. But, I figured that both my gps and Mapquest told me the same route, so it must be right. Come to find out??? I could have just stayed on the Turnpike, right into Pompano...would have dropped me about 2 miles west of 95!!!
You will find everything incredibly well marked in Florida....so, as you leave FtL, obviously head west. Most of the main drags will get you to the Turnpike.
But, I have to tell you....I will never, ever take 95 while in Florida again. I even avoid it once I get to the coast....take Rt 1 pretty much...or 1A...slower but much more pleasant!!!
It does, in fact, take just over 3 hrs...driving at a reasonable pace. I think I could do it faster now that I've done it before and am more familier with the roads in that area.
