We usually arrive around 4:00 pm after driving through the night, and nobody is exhausted, just ready to get out and walk around. We first stop at a grocery store just outside WDW property before checking in at our resort. After checking in we shower & change, then go to Downtown Disney for dinner and to walk around. With the exception of taking Amtrak's Auto Train in 2008, we have driven from the Philadelphia, PA area every trip since 2002. I wake up around 6am the day we are leaving, then go back to bed around 4-5pm and sleep until about 11pm. We leave around midnight and drive straight through on I-95. My wife & kids (now 14 & 15) stay awake that day until we leave, then they sleep in the Avalanche and don't wake up until we are in North Carolina where we stop for gas and a Cracker Barrel breakfast around 7am. We then hit the road again, only stopping for one more gas stop and when bathroom breaks are needed. The trip lasts 16 hours, + or - 1/2 hour. By leaving when we do we miss all of the morning traffic in the northern section of I-95 (especially around the Washington DC area), and when we stop for breakfast we avoid a lot of the traffic during the morning rush. The long drive and hours aren't a problem for me since I work rotating shifts and spend up to 13 hours a day in a vehicle and am used to being awake all night in a car.
