Question: Stadium and viewers?

[Stivri]

Yes, it is obvious, but the game manual must have precise instructions and where to find all the answers, such as my question to visit the stadium.
I did not know that Level 5 has a limit for visits of up to 14,500 (as you wrote) and I don't found this information and I would not unnecessarily spent money to build a stadium of 43,000 seats!
