PATH will follow the schedule you see on the PATH app or CityMapper app, if you plan for it then there's really no problem. The questions are a) how far / how many transfers to your fav haunts from the PATH stations in NYC and b) how far from PATH would you be living in JC? If you're relying on the Light Rail to get home once you get back into JC, that's a crapshoot late nights and weekends. If you're within 10-15 minutes walking from a PATH station then you're in good shape.

And probably sooner rather than later you'll find a bunch of places that in JC you really enjoy and spend less time in Manhattan than you will when you first move here.
