We have driven quite a few times from South Jersey to WDW. We can make the trip in about 15 hours. We have left home at 4am, and pulled into WDW around 7pm. The kids travel really well, and we make sure that rest stops are gas/bathroom/stretch the legs combined! (I think DH actually times us to get us back to the car quickly!!

) On the way back we usually leave WDW in the early afternoon, so we generally stop in SC, and then have about a 10 hour drive back. We'll be driving to WDW the Thursday before the cruise, and driving home a week after we disembark. The parking at the port is sooooo easy and our parking spot was so close! We were parked only about 100 feet from the Magic!
