I went there 3 days ago, very bad experience. All the people have to put all the belongs except sunglasses in the locker, means you can’t take any photo by yourself. After 1.5 hour waiting, I saw the reason of long long waiting line. There were 3 photographers on the skywalk. They release people one by one family. Every family was asked to post for photo shooting, about 5 photos each family. The photographer took 3 photos of us and we rejected to take more, then he let us go. After the 3 mins free time on skywalk, another staff asked us to select our family photo at the exit. We didn’t go to check our photos because we were feeling bad about their arrangement. I would said the skywalk ticket is not a necessary, general admission ticket is good enough. It is because the second sightseeing spot ( there are 2 stops) is very good which is similar to the skywalk.
