My first VR experience at a theme park was in Pleasurewood Hills in about 1991, was a headset, moving chair, and glove to interact in the VR world. So it's been about quite a while!
I get what you are saying, and I'm sure improvements will come, but all the time you have to clean headsets between one sweaty punter and the next (and realistically, that will always be the case) VR will forever remain too labour intensive, too low throughput to be a real mainstream part of theme park line ups.
What Europa have done with CanCan seems spot on; dedicated station, ride vehicle slips in between the standard ride vehicles, pay per ride, VR experience beyond the actual coaster (getting on the ride vehicle in the VR world ? ), and fun once it's running. They've got it right where DBGT and Galactica got it very wrong in the era of the same technology, as has Dr Archibald. It's going to work much better in a pay per ride situation like this.
