I've been up in the real Eiffel Tower a few times, so I had to cross this one off my list. Locals have a discount, so even better!
I asked a bunch of questions about construction and the scale, but no staff were able to answer. So, that's an area of improvement. I can't be the only person who wants to know the scale.
The observation desk is really tiny. So, if you don't like closed spaces, this may not be the best for you. They could also improve by providing information signs to explain what you're looking at.
