We are 6 hours away and we've done it several different ways.
On our first trip with our oldest (he was 16 months), we drove a little more than halfway the day before, stayed overnight using points, then got up and drove the rest of the way the next morning. He took his morning nap in the car, we arrived at the resort around lunchtime, checked in, had lunch, and went to a park for the rest of the day. We've done that on other trips, too, like the time we were meeting family who were arriving shortly after noon. We drove a little more than halfway, stayed overnight and drove the rest of the way the next morning.
We sometimes leave around lunch-time and arrive just after dinner, check in, get settled, maybe hit DTD, and get a rest for the next day.
Most often, we leave around 8:00, get there right at check-in time, get settled in, and half the time we hit a park, half the time we don't.
There is no way we could get up and leave at 4 AM. We'd all be tired and grumpy and even when my kids were young like yours, once they were awake, they would have stayed awake awhile, then been grumpy because their sleep had been interrupted. I vote for driving part-way Friday night, staying overnight and going in Saturday morning ready to play. The excitement of getting up and knowing you're headed to Disney is awesome. Everyone is happy and chattering about what to do first and what they can't wait to ride. I'm thinking about talking my husband into going halfway for our next trip, just because our reservation starts on 12/31 and I'm afraid traffic will be bad that day so I'd like to get a good jump so we can get there early.
