Road trip time, Cobourg On to Toms River NJ

Heading down to Toms River NJ to visit some friends leaving about 5-6 am
Cobourg is across the lake from Rochester
It will the first trip with the Prius, looking at about 824 km trip which will be a walk in the park, on the August long weekend we drove the Bimmer convertible to Dartmouth NS which was 1600km trip and it took us just over 16 hrs to drive.Total stopping time 27 mins, dont you love the info a GPS will give you
How much are the tolls roads?
We will probably take 81 the border to Scranton , then some side roads
Or is it better to take 476 until Phil and take 276 to 195 to the coast
We have never been in that area of the States
Anything to look out for?
How many miles over the speed limit can you go without getting a ticket?

~10-15 mph over and you shouldn't get a ticket. However, who knows if you'll get "special treatment" based on your plate..

I'd use the Google maps route. Few tolls if you go that way.. not until you get onto the GSP.. I think it's two tolls, one US$1.00 and one $0.35.
