I spent RMB150 to get up to all 3 observatory cabins in the Orient Pearl Tower (东方明珠电视塔). The view was fantastic but the queue to go up or down of each observatory cabin was mood killing. The conclusion was you should only get the RMB100 ticket up to the 2 observatory cabins instead of all 3 as the view are the same, plus it would be a clearer & cleaner view from the windows at the 2nd/largest observatory cabin. Well this is just my personal view after paying the full price ticket. Hope it will help some people to save some money & time next time.
