I enjoyed the ride until the backwards in the dark part. I agree with the sensation of going upside down. I actually thought we did, we didn't. I get very disoriented when I cannot see. This also happens to me on water rides that are in the dark. I am unsure if I will do this again. If you have vertigo I would think of avoiding it. Or try it at the end of your day and if it does happen you didn't ruin your entire day.
