The green vs. orange must be a new thing. When I went last year, they did not have it. I was so worried about Mission Space after that child died on it shortly before we went. So my mom, sister and I all rode it first to try out. Well, we had no problem and suggested that my dad and son ride it. While my son hated the ride, but couldn't exactly place what he did not like about it. I think he said something like it made his head feel heavy. My dad got really sick. So I guess it depends totally on the person.
