Hi, I am usurping my husband's computer time here to tell you about my experience with Mission Space.
Uncleromulus and our two friends bowed out of taking the ride last week when we were at Epcot; however, I just couldn't pass it up. I was pretty nervous after having read everyone's experiences at this forum. Also, as you are about to enter the pavillion you see the warnings about high blood pressure, heart problems, etc. -- which is pretty much par for the course at many of the rides at Disney; however, there were so many warnings even inside the ride that I was beginning to wonder if I were wise to take the "mission" on. Fortunately, I met a very nice fellow in line who was also new to the ride and whose wife had also opted out of the ride, and we pretty much talked about a variety of topics to keep our minds off what might be waiting for us! (It also helped that there was another couple in line about my age who had taken the ride already and called it "fantastic" and warned me to keep my eyes centered and open during the ride.)
Well... with some trepidation, I was finally seated and ready for take-off. I kept my eyes focused, and must admit I wasn't cognizant of the sensation of spinning. And the g-forces weren't as bad as I feared they'd be. I will say, however, that the first few seconds of the ride are INTENSE and I did feel slightly queasy for a second or so -- but this passed very quickly. And then I just found it to be incredibly fun. A great ride. I LOVED IT. I would have gotten on the ride again had it not been for the fact that Uncleromulus and friends were ready to move on after having waited for me to have my "mission" experience.
I think it was more nervousness than the ride that made me slightly queasy for the first second or two of the ride. With all those warnings posted outside the attraction and then during the pre-ride movie and then the offer to "opt out" right before you board the simulator -- well, who wouldn't be nervous?? My new friend said the ride made him a little queasy, but he had eaten 30 minutes before taking the mission. (Not a good idea.)
I would recommend the ride to those who don't mind spinning rides. I like the Primevil Whirl (the spinning roller coaster) and all the simulator rides at Disney so the ride was a good experience for me. I told Uncleromulus it was NOT his kind of ride -- he hates spinning and simulator rides.
I'd give it a "thumbs up."
