I'm still trying to decide for our first family road trip in August to WDW what our driving plans should be. Our initial plan was to leave at 5am on Thursday from NY, driving 95 all the way, stopping at a hotel in Florence, SC around 5pm. Then the next day starting at 7am, arriving at WDW around 2pm. Then after speaking with friends and reading other posts here, another option arose that DH and I can't choose -- driving straight through starting Wednesday evening around 6pm, arriving somewhere close to WDW at noon and getting a cheap room for the rest of the day and then be at WDW bright and early on Friday. This option would give us an extra full day at WDW (which I already have park tickets for).
The dilemma is really about our kids. All that time in the car while they are awake might be torture for them, and in turn us. But if we go straight through, it might be harder on us staying up that whole time (I doubt that I could sleep while my DH drives -- I'm a control freak and need to know what's going on at all times).
All advice is welcomed!
Not knowing any specifics on where you start from, or your 'driving style', I won't try to figure how I-95 daytime traffic will impact your drive across the 2 day plan. I will offer this opinion:
The driving at night is a great way to avoid much of the daytime traffic problems. Our kids usually sleep through a great deal of the night drive, making it much more pleasant for me doing the driving. There is less traffic on the road (overall), and you are less likely to encounter traffic problems along the way (generally speaking). We have done similar to what you have laid out, and gotten a cheap room for the night before our stay began, and it has worked out well for us.
That being said, only you know if driving all night will work for your family. With 2 drivers, and the ability to switch off during the drive as needed, I would say an all night drive is certainly do-able.
If I read your post correctly, the overnight drive puts you at WDW around Noon that Thursday. You will be zonked from the drive, so if all you will do is eat dinner, hit the pool, then sleep for the night, then really you are only gaining the WDW time from Friday morning at park opening until 2:00 p.m. Friday (which was your 2 day arrival point), or about 6 hours. Consider that in your planning comparison.
All in all, if it were me, and I had 2 drivers available, I would do the all night drive. The kids sleep alot more, and the car is quiet and less stressful. I'd get a room upon arrival, catch a much needed nap, then head out later for some park time or fireworks, to make some use of getting to WDW a day early. (I've found that I can't take more than 3 hour nap after an all night drive, or it screws up my regular sleep pattern the next few nights. A 3-4 hour nap lets me rest, and doesn't throw my internal clock off too badly for those next few days.)
Whatever plan you decide to do, travel safe!
