Personally, I liked to arrive in Orlando on a non-nocturnal schedule, bright-eyed, bushy-tailed and ready to hit me some parks. If I didn't do three days of driving, I did the huge chunk on Day One. My favorite way, though, was to bang out six hours or so the first day, do a normal amount of driving the second and the last little bit from Kingsland on our first park day.
Day One - up before the sun and on the road. Drive to the bottom of Georgia, stopping in Kingsland, just minutes from the Florida border. Grab fast food dinners for everyone from wherever they wanted (Kingland has them all, right off the highway, as well as ever chain motel, I think) and Dairy Queen, whatever they wanted. In bed EARLY...like 8:00.
Day Two - up, in the car and on the road around 5:00/5:30. Make rope drop. Check into hotel in the afternoon. I clean room, put stuff away and iron while kids swim. Nice, early dinner in Epcot, leaving well before fireworks. OR...IF THE ROOM ISNT READY...
Everyone goes to the pool, dinner at the hotel, then kids back to pool while I put the room together.
Either way, we are in bed early after all that and well rested for the next day.
