Both are rough rides. I feel like RnR is much more fun, and SM jerks you way more. RnR as long as my head is back I have no issues. SM I’m not much of a fan of, I always feel like it’s going to hurt my back (although it never has).
You won't though. Rollercoasters undergo something called "envelope testing" and it makes sure that you cannot hit your head or arms on the structure - even when it looks like you can. They sometimes purposefully make it look that way to add to the thrill, but you can't. It is very safe.
It really is impressive....I don't find Space to be great by 'ride' standards. It seems like a Crazy Mouse type ride found throughout the country. But, somehow, it's such a different experience and the theming really excels on this one.
I don’t ride either one. Aerosmith gives me a headache and Soace Mtn hurts my whole body lol. My family all prefers Aerosmith out of the two though. My kids are always scared they’re going to hit their heads on space mtn lol.
Space Mountain is really rough on my neck and it’s hard for me to get in and out of my seat (I need both my knees replaced). I do ride it more than once each trip because it’s a classic.
RnR is a more fun ride (IMO) and has a seat that I can press my head to the back to prevent my neck from getting whipped around as much. I also like sitting with my DD or DH when on the ride.
