I live down in Miami and when I was younger I used to do several one day trips throughout the year.I would get up at 4am drive to Orlando spending the day at the parks leaving and driving back to get home around 2-3am.Basically almost 24 hours and I acknowledge it was insane.I stopped doing it about 5 years ago,just not safe and you grew to hate the drive.Now I go and stay a minimum of 3 days.I think I did that drive so many hundreds of times over the years that today I don't even take the turnpike or 95,I go up US 27,takes longer and goes through some ugly towns around the lake but overall is less stressful,not as boring,free and from Sebring north there's a bunch of towns and places to stop to eat.Also once you get to I-4 you're basically 5 minutes away from Disney.
