Please don't meet me up here
Only do this place if your heart is set on going up the Empire State Building, just because it's there. My heart was set on it, so I guess it was worth it. Maybe. I bought my tickets online, but I honestly don't know if it saved me much time. Basically, it's a tourist trap and you will stand in line for a very very long time surrounded by other tourists. At first you will be in hallways and rooms that are beautiful, but after you are ushered in and out of an elevator taking you to the 80th floor, you will then spend a great deal of time in a very ugly room (more like a gigantic cattle car) where you will be subjected to having your photo taken against a 'green screen' so that you can be asked to cough up more money for your very own face superimposed against the Empire State Bldg., and will also be asked to buy an audio tape that will describe what you are seeing. I said no to both, as well as the virtual Skyride. Lord only knows what other stuff they have planned to sell in the future to us gullible tourists.
Eventually you will be ushered into an elevator for the 86th floor, where you will go through a gift shop, out to a small open area where you can see Manhattan at your feet, between metal bars (fortunately, the bars are well-spaced, so you can truly see things -- plus, there are viewing machines that will give you a bird's-eye view for some spare change). There will be many people up there doing the same thing, so it may take a while, but eventually you should be able to shuffle to all four sides.
This was the only over-rated, over-priced, touristy thing I did in New York, and my daughter kindly humored me with nary a complaint. But if I had spent all of our 3 days in Manhattan doing these types of tourist stops, I think she would have choked me.
