I wouldn't do it unless you were a drivable range, such as Jacksonville to Port Canaveral or Dallas to Galveston. If there's a problem on the flight, you'd still have time to drive to make the ship. Otherwise, it's not worth the stress. Several years ago, there was a lot less stress. We've done it once, flying out Saturday morning after our Friday night wedding. But we left at 5:30 a.m. on a direct flight with two other direct flights that day before noon (which would have still gotten us in on time). As a result, far fewer worries. Now, with so many less flights, there are only three direct flights to Orlando from our home airport on a Saturday to begin with and I'm not even sure the first one would be doable. Definitely not any of the other ones.
