I have a city pass how do I make a reservation to empire state building?

Do it in the website

Make a free timed reservation on their website, ignore the 100 people on the line, present it to the security guard outside, get inside. Go to the express lane and scan your NY Pass. People stay outside because they don't ask, you should have priority with your pass.

They have a website

You should be able to do it in the App

Good
