Ride in front. That might seem counter-intuitive to roller-coaster aficionados, since riding in the back tends to whip you around quite a bit more. But the cars at Space Mountain are so short that there is virtually no difference in this sense. And that being the case, there are a couple of good reasons to ride in the front row. First, riding with nothing in front of you removes the sense of security you'd otherwise have by sitting further back, which provides an additional adrenaline rush. And, you're first up as you approach the camera's flash at the end.
