This was always on my bucket list when visiting New York and it was amazing. However a few tips before booking this. There is no information once you've entered the queues, if you have elderly relatives, small children or any health issues, you could be waiting a very long time standing, there is no information given to the length of the queue etc and they seemed to go on forever, one after the other, some waiting time information would have been useful. A bit chaotic getting to the top.
However once you've waiting and gone through the queues and security it is well worth it. Not great if you don't like heights!
The views on a clear day are spectacular and you can see for miles. It does get very busy at the top as you would expect but worth every penny.
We went early morning and were at the top in around an hour. The history of the building was a nice interesting touch on the way up.
The beautiful Art Deco of the building is amazing, such an iconic building you simply must visit.
I would definitely go back during a sunset.
