Hi...fellow Jerseyan here (albeit I'm from the extreme Northern end of the state)...
Hmmmm, I see you're in Cape May...to avoid city driving, and assuming you just want to get there quickly...I would do the following (sticking to interstates the whole way)
* GSPkwy North to 1-287 at exit 129
* I-287 North to I-80 West
* I-80 West into PA; to I-380 North
* I-380 North to I-81 North in the Scranton area
* I-81 North to Syracuse area
* I-90 West (NYS Thruway West) to Buffalo area
* I-190 North to Nga Falls area
* crossing into Canada may be easiest at the Queenston-Lewiston Bridge
* for a great N Falls experience, stay at the the N Falls Marriott or Embassy Suites...best views of the Falls imho
Have a great trip!
Fellow Jersey guy!
The cities mentioned are not large and easy to negotiate while on the interstates...total drive time will be about 10-12 hours depending on how often you need to stop.
