We drive to WDW from Ohio, I think it is 840-ish miles. It takes 14-15 hours, depending on stops, but we don't mind it. We typically leave around 3 in the afternoon and drive straight through. We much prefer driving over flying; I hate to fly, but DH and the boys don't mind it. Our kids are older now but have always done well on long car trips. We live three hours from the airport, and that is a hassle in itself. If (like last June), we end up with an extra day off before we were planning to leave, we can leave a day early. We can pack whatever we want, doesn't matter how much the suitcases weigh or how many we bring, we can bring a laundry basket or two, we can arrive when we want, and leave for home when we want. If we were planning to spend a full day at a park before starting home, but decide we want to get on the road, we can do just that. If we were planning to leave after breakfast but somebody wants to go back to Epcot for a few hours, we can do that. Plus, it only takes about $150 for gas each way; much cheaper than airfare for 4.
