For those folks incorporating some driving into your upcoming itineraries - I've seen a few people say they're going to drive to Pennsylvania or to Washington D.C. ...
I'm a big fan of building itineraries that involve thinking outside the box. My partner and I planned to spend part of the holiday weekend in Philadelphia visiting Independence Hall, the Liberty Bell, and the museums (Philadelphia has some amazing museums). We picked up a rental car in Manhattan and returned it in downtown Philadelphia several hours later. Parking in Philadelphia is expensive and we didn't want to drive back so we took Amtrak (the train) home at the end.
Personally, I find a little piece of me dies every time I have to stop at a New Jersey Turnpike Service Plaza. We drive to Baltimore and Washington D.C. sometimes too and often our strategy is to get an early start, beat the traffic leaving the city (if it is a weekday) and then stop for breakfast once we're a ways out.
We found this place called Daphne's Diner this past weekend - a true Jersey Diner - in Robbinsville NJ. It is extremely convenient to the Interstate 195 exit off the NJ Turnpike (same interchange as for Six Flags Great Adventure). Exit the Tpke and bear left for "west" and then immediately get off 195 onto US 130 North and the diner is on the left. Cool place - good breakfast - nice staff - no wait.
That was fun. I was recently giving advice to a guy driving to JFK Airport from Pennsylvania - I wish I could have recommended Daphne's to him but that was before our discovery.
Also, for those driving to D.C. - no sales tax in Delaware (keep that in mind if you're planning to make any big ticket electronics purchases)
