Why have we driven to WDW 25 times in the last 10 years? Perhaps our recent flight from San Antonio (we were there for a book signing) explains it best:
[careful packing of the suitcases according to TSA rules with approved locks]
11:00 a.m. departed hotel in cab
11:30 a.m. arrived at airport (baggage check hassles, multiple times through security, the wait for the flight, overhead bin battle, the wait on the tarmac)
2:00 p.m.- 6:30 p.m. (one hour time zone adjustment) the flight itself: fresh air, roomy seats, quiet passengers, large bathroom facilities, abundant food and drink, etc.

6:30 p.m.- 7:15 p.m. tarmac ride to gate; retrieving baggage
7:15 p.m. - 7:30 p.m. the wait for the limo
7:30 p.m. - 8:45 p.m. the limo ride home
Total time investment for the 3 1/2 hour flight: 8 hours and 45 minutes.
["Oh, why drive to WDW when you can fly there in just three hours?" NOT!]
In several weeks, we'll be driving to WDW!
All the best.
