Hi - we are traveling from Argentina to Minnesota and are considering flights with a 21 hour layover in JFK. Flight arrives 10am with final flight leaving next morning at 7am. Looking at staying in a hotel near the airport for ease of getting back in the AM. With international arrivals, luggage accommodations, etc., would we have enough time to see SOMETHING in NYC (Ellis Island, Central Park...) before hitting the hotel for sleep? Thanks for your help!!
