At the end of March we'll travel from NYP to JFK at about 7:30 - 8:00pm. We used the subway around New York City last year and found that easy to use and interesting. This year we are travelling with a moderate amount of baggage directly from NYP to JFK.
Do we use the subway which we know takes longer but are familiar with or the LIRR which is faster but may also have an advantage and be interesting in a different way to the subway?
ps: Any recommendations for an early evening meal before we are off to the airport within say a 10 minutes walk of Penn Station?
