This thread is an example of the best part of these boards--real life practical advice on issues not addressed in the brochures. I have a 500 mile trip to Port Canveral from Atlanta, and I even split that up on the way down. Wait until Traffic dies down on Friday evening (for those passing through Atlanta on I-75 or I-85 or I-20, be advised that our rush hour begins at 3:30 or so and lasts for nearly 4 hours!) and then drive to Jacksonville, 350 miles. I could push it through to the Port but then it becomes seriously late.
The next day is Embarkation day, and it is a 150 mile straight shot down I-95 to the Port, so we will be there when boarding begins. Did the same drive last May for the 4 day Wonder, and it worked very well. The tough part is the full day 500 mile drive back home on disembarkation day. About 8 hours unless you time it awful with respect to Traffic. I know others are driving farther in one day, but Oy! I'm gettin' too old for that.
Message to Connecticut--I grew up in CT, and can't believe you drive that straight through. Wow.
Just remember that unanticpated things happen on the highway--like the car I saw get damaged on I-75 last night when a piece of debris fell off the 18 wheeler in front of the car. So most everyone here is giving the right advice--dont leave yourself too far on Cruise day.
To all fellow drivers--arrive safe & sound, and not too tired to enjoy.
