Please do not attempt to do this in 3 driving days with a wife and three kids in the car. From LA, it's a shade under 2600 miles to Kissimmee -- and from 42 to 50 hours of driving. You're talking 13 -16 hour days in the car. If you were by yourself, I'd say give it a try, but you are going to make your family miserable just TRYING to do this. Just my opinion. Bob
