I drive from Rhode Island to LGA and JFK weekly. Without traffic it can be done in under 3 hours to LGA little further to JFK. Not short enough to sit reserve at home but its easily commutable on day of since your driving. you just need to avoid it at rush hour through Connecticut and your good. Best time is when you get off work late at night, can make it back to RI in 2 hours 30 minutes if you drive fast.
