Hi Sandra. We have drove 5 or 6 times and the last two have been with the kids (ages 5.5 and 4). We always drive straight through from Kingston unless we encounter a really bad snow storm or freezing rain. On our last trip, we left home about 11 am and we arrived about 2 pm the next day (27 hrs). On the way home, we left Disney at 7 am and were back home just after 8 the next morning (25 hrs). We usually stop about 1 hour for meals and then for some stretching/fresh air at the rest stops along the way besides the gas stops.
As far as the driving goes, I find that after the first 4-5 hours, the time really seems to fly by (especially at night). I do most of the driving and as others have said, it really isn't that bad. My wife will stay awake most of the night for company and then she will sleep for a few hours. I find that I usually start to get tired as the sun is rising. My wife will drive for a few hours while I sleep and then I usually finish up the trip.
The kids travel really well... a lot better than either of us could imagine. We take a 13" TV/VCR combo and that is worth its weight in gold. We also have lap desks for the kids so they can colour, read books, or any number of things. We keep a cooler with us as the kids are always wanting something to drink. Both kids will sleep right through the night even when we stop for gas, and in the daytime, they love seeing all new things along the way.
My wife was concerned about driving through the night as she was worried that we may not be able to find any gas stations open and therefore she had me stopping whenever the gas guage would drop down near half. This really isn't a concern... there are many 24 hour gas stations along the route (81 to 66 to 17 to 95 to 4).
Don't dismiss the option of driving too quickly; we were apprehensive too about driving straight through, but now we wouldn't do it any other way and kids seem to be very adaptable. We normally stay 10 - 15 days and our next trip is for 17 nights, so the extra day or two for driving isn't a factor. If you only had 4 or 5 days then driving may not be the best option. We look at it as the money we save on driving vs flying allows us to stay that many more nights at WDW.
Have fun whichever option you choose.
