The SkyView is basically just a big Ferris wheel, but it gives a nice view of downtown Atlanta. Here's a video of the experience.
There also are some perks: The cars are enclosed, and you can bring beer and wine on board. And given that it's Atlanta, there's climate control.
It even has an optional VIP experience that lets you take a longer ride. But I think I can safely speak on behalf of most Ferris wheel patrons in saying that few people wish their ride were longer (especially when you're stuck up top waiting for people to get off).
