Well we are defiantly glad you are still coming If the GPS says 4.5 I am guessing you live closer to NY. What we learned is that the road where pretty good coming down 95 but you will spend most of your time in New York traffic. If you have Easypass for traffic tolls will make it more palatable and there are some tolls with traffic. I would add 1.5hr to your trip. Nothing to be nervous about it is a strait shot just keep a lookout for signs in NY, as far as I know you are only going over bridges and you can tow over them. Just take your time and be safe.
