Not all tickets here are created equal. The basic-priced tickets let you either walk or take the elevator to the second floor viewing platform (yes you pay more to take the elevator), which is actually at 116 meters, so still a great view. If you want to go all the way to the top (276 meters) of the tower, which is a very cool experience especially at night, you will pay the most. The top can be accessed via lift, however, which is a plus.
