If you really want speed from Daytona Beach to WDW, you would go south on I-95 and change to I-4 as usual, but shortly down I-4 get off on Toll 417 (Greene's beltway) southbound (long before downtown Orlando).
This takes you around the horn to the east of the airport. Get off 417 onto Osceola Parkway (exact change exit toll booth there) and it is a straight shot to Animal Kingdom.
At several toll plazas you must take what looks like an exit ramp to pay in cash; the main lanes are for Florida electronic tolls only.)
The slowest part of that journey is from the Daytona Beach sand just above the waterline onto the main drag out of town.
