Before I went to the One World Observatory, I was checking out the 9/11 museum, which I would highly recommend. I purchased the ticket that allowed flexible entry from 4 pm - 8 pm. If you ever go, I would highly recommend that ticket pass. They work up some hype in their ads about how "You take a Skypod to the top" when it's really just an elevator with a screen on it. The screen shows a pretty cool display of New York City throughout the years, but I wouldn't be so hype to call it a "Skypod". Once we got to the top, before we even saw a window, we had to watch an entire video about what it would look like when we saw a window. Then, for about 4 seconds, they released the screen, and let us see the actual summit, which is quite amazing. Then, they have you watch an entire video about how the iPad works. The iPad is totally overrated. If you're like me, you came to see the real views. The iPad, which is included in the ticket type I bought, is supposed to show you into the distance, things you couldn't see with your eye from the top. The iPad supposedly follows you and shows you real-time imaging about how it looks like. It does/doesn't. It's calibrated like trash. I followed all the instructions, I stood exactly on the calibration spot, and it still failed. Eventually, I just stopped using the iPad. Then, when I finally started looking out the windows, it was so packed. I guess they don't cap the number of people they allow at the summit, so it's super crowded. It's really hard to get to see a spot at the top of the summit, and personally, I only stayed up there for about 15 minutes. So I ended up spending $55/person for a 20-minute experience. So, the views are great, but they let in way too many people, and too much of the tour is virtual.
