I voted for Space, but it got me thinking about the question. We often use the term "attraction" for Disney vs. "ride." Some people say that the terms are one in the same, while others say that attraction is for the entire experience, while the ride is only the physical ride within. Others say that the word "ride" is more for a fair or even Six Flags, since it doesn't really rely on much more than the physical ride. When it comes to these two...RnRC is technically a more thrilling ride, but the recording studio and queue don't really do much for me. Space does get the benefit of nostalgia, but there's still something very NASA meeting 2001 Space Odyssey as you climb towards the boarding area. The queue soundtrack, the little games and visuals along the way just feel like you're building to something special. The exit also still keeps you in that space vibe.
