We've done both, drove down 2003, 2004; flew 2006. Some points;
1. Driving from NJ takes 19-21 hours. If you drive straight through you'll need to leave at 7:00 Pm the night before. If you break up the trip, it's best to leave very early (2:00am) to get past Philly, Baltimore, DC & Richmond rush hours. We left at 2:00am and were in Santee SC by lunch. Then the next day it was 8:00 hrs to WDW
2. Flying is what I prefer. We fly out of Atlantic City on Spirit

. We leave freezing cold NJ

around 7:00AM, arrive at Orlando Airport around 9:30Am and are lunching pool side in the sunny weather

around 11:00AM! Plus a seven day vacation is just that, 7 days. You don't waste 2-4 days in the car.
Unless my DW gets an urge to drive (ride, she never drives!) again, flying is the only option for me!
