I would recommend spending the extra to go up to the top floor. Some fantastic views (even on a rainy day!) You don't understand the scale of the structure until you've seen it....also it's 300 steps to the first floor, maybe not suitable for everyone, there Is a lift (which costs a little more!) Well organised, and you need to go through security before getting in. 100% recommend a visit! :)
