They're both really big screens showcasing (admittedly breath-taking) views of the wonders of the world. I'd even add with a handful of "4-D" effects, and cameos from fan-favorite animals like polar bears and elephants. Granted Soarin' is a mix of man-made and natural wonders, and AP is just less recognizable natural landscapes, but to me, seeing them back to back would be like riding Spidey and Transformers or Kong and Supercharged back-to-back.
