If you get a CityPass, the Skydeck is included and you get to skip the line
During the week. We went on a Saturday morning 9 AM, there was a 2.5 hour wait. 🤔
The best time is between 10 am and 11am. I went around 1030am and it was not busy.
I went during around noon time and it was pretty crowded. I think early morning is a good time to go.
