Felt rushed (and a bit luck-dependent).

They say up front that the tour is 50 minutes. Not mentioned is that 50 minutes includes waiting in line to get photos in front of a green screen, waiting in a TV room while others do the same, long travel times between limited locations, and a 5 minute "CNN is really great" video at the end.

The part that might have been the most interesting to me would have been listening in to the control room and watching the monitors as they switch between cameras. Except in the 20 seconds we actually listened, they were playing an external feed so literally nothing was said. Perhaps another group would have been luckier. But I would have waited around 20 minutes to actually get some behind-the-scenes info. No such opportunity here.

Next was a demonstration of Green Screen. A fine thing to include, but not impressive enough these days to be a highlight.

They we progressed down several floors, staying in public areas and looking through windows at studios and the news room. This is the bulk of the tour, and while some studios may be working and others not, the time and limited angle reduce what can be observed anyway. There are tidbits like the cost of robotic cameras, but you are very literally just peeking in a window.

The last bit was a view over the food court with some history of the building and the fact that the escalator we went up in the beginning is the longest freestanding one in the world. Neat facts, but you're not seeing anything you couldn't have seen without the tour.

Overall maybe you'll be luckier (or your tour guide a bit more enthusiastic). But I felt the tour wasn't worth $15 and mainly rushed people through to try to sell them $30-40 photos at the end. Go in the building and wander around the public areas, but consider the tour optional.
