Hello, driving down from Canada for weekend trip to NYC in May. We plan to spend one night in Tarrytown and then take the train into NYC for two nights (Sat and Sun), traveling back to Tarrytown Monday morning and continuing home. Does anyone know if we can leave our car in the train parking lots over the weekend? I see it's free parking Sat and Sun but not sure how it would work for Monday morning or even if overnight will be an issue. Also, are the lots fairly secure/monitored?
