Looks like you had a nice time in NYC. I live not far outside NYC in NJ so get to go into the city quite often. One nice place to visit and walk through is Central Park. Take a subway up the west side of the park to the northern end and spend several hours walking south and explore what is in the park. It helps to have a park map or access the park map on their app. Great place to send a beautiful spring day. i like to end my walk at Columbus Circle which is on the extreme south-west side of the park. Lots of subways available from that location.
