@tricia300, I was in New York last August and I am going back again this year. Have you walked The High line or Brooklyn Bridge, what about taking the FREE Staten Island ferry for a view of The Statue of Liberty. Did you go to 'Ground zero' or the One World Observatory. Did you go to Chelsea or Greenwich Village? Without knowing what you did on your last trip, it's hard to give recommendations but if you did none of the above, you missed out.
The highlight for me was The High line. As we approached the 'Meatpacking district' end, there is a distant view of the Statue of Liberty. That as a heartstopping moment for me.
We never walked Brooklyn Bridge because we got there at the end of a blisteringly hot day and I was too tired. I did go by myself to the south side in Brooklyn and walked down to the waterfront for a glorious view.
