Here ya go! Circle Line it goes around Manhattan..I think you can combine it with a ticket to the Statue of Liberty..save some $$$
I'd walk across the Brooklyn Bridge...you'll want to stop and look a lot..also, it can be pretty crowded..
Hope YOU like steak... Peter Lugers I expect a written report when you return..
Have a great trip..and congrats to your son...what are his plans?..job? grad school?
Hint on Peter Luger’s: Their best steak is the Porterhouse for four people, so go with at least four and order that.
