I think I read someone's account of it somewhere, and it sounds like it was pretty bad--no motion base or effects, they'd just sit you down in a chair in some backstage room and have you watch some educational video in VR. Almost sounds like it wasn't even intended for guests..? And the worst part is it was a $10 upcharge. I do think VR has a lot of potential and I hope the park can introduce a proper VR-based attraction closer to Battle for Eire... this just wasn't that lol.
Another thing in Ocean Explorer that used to exist is a projection mapping show on JTA. What ever happened to that? I've seen a few videos online and it actually looked pretty cool, and I think the projectors are still in place to this day.
