I usually get on Rt 1 a little south of Rte 18, go thru trenton ( saves a few miles from getting on 95 near Quakerbridge Mall) and get on 95 near Sesame Place. And keep going south on 95, till I get to Florence SC. Then I stay at the Thunderbird Motel for a night. The rooms are serviceable, and they have a great all you can eat hot / cold breakfast buffet. From there it's only about 7-8 hours to WDW ( I found 65-70 MPH, an average speed, more in SC, and FL if you don't see the police). They also have a bunch of discounts ( AAA, EMS, others...at the Thunderbird). We'll be drivng down in January from near Princeton, if we see any long term type of constructions, I'll let you know.
