I would like to visit a Cinerama someday, but I'd have to go solo. My wife and I went to a similar venue in the Wisconsin Dells many, many years ago. It had a 180-degree view, and here were no seats, it was standing room only. There were waist-high posts scattered about that you could steady yourself with, but the effect was unnerving. One couldn't help but lean into turns for the short movie, and some people would lose their balance. My wife couldn't watch for more than a couple of minutes without feeling like she was getting sick, so she'll never return to that kind of experience.
It was pretty remarkable, though. It would be fun to see an actual movie like that.
