Depends on day, time of day & traffic conditions. They have a good bus service & there's a bus stop right across from the hotel
Newark easier,but JFK flights might be cheaper.
By bus it will take one and half hour to JFK. We had taken bus from this hotel to bus terminal in NY. There are buses to jfk every half an hour from bus terminal.
It is 30 miles. Probably just over an hours drive, though I would watch the traffic very closely.
