Just What You Expect
This tour was like CNN itself: What you see is what you get, and that's neither a good thing nor a bad thing.
The highlights of the tour include the demonstration behind the production of the broadcast, including showing 12 live screens, and an overview of the studio explaining the roles of writers, producers, anchors, etc.
The tour can get lengthy in some parts (an HOUR to go through a news studio?), but can get informative.
Tour guides do a good job, at least the ones we had.
