We bought timed tickets to let us in at a certain time. Some technical glitch happened with the turnstile where you scan the tickets and it wasn't working. At that point, things became utterly nonsensical, as we had our tickets printed, with our time clearly visible and they wouldn't let us in and we had to wait. Fine, but then when the turnstile was working again, a bunch of the walk ins were let in before us despite our timed tickets, so that was a bit frustrating. We went in the hot sticky summer months, so there was some haze that dimished the view, but it was still worth it. Plus, the breeze you get up there is such a nice cool off from the oppressive heat.
