What you’re describing is — almost exactly — like how the Rollercoaster Tycoon series works. You can click any visitor, and see all the stats for that individual visitor, including how happy, sick, bored, etc. they are. You can even see them saying things like “I reall like Rocket Coaster!” or “The line for Very Merry-Go-Round is too long.” Then you can aggregate how many visitors are saying each thing about the various attractions or the park in general. And then it allows exactly what you said: make tweaks based on the aggregate feedback and see the positive (or negative) effect your tweaks have.
