Agreed, it feels like if they're going with a flying broom attraction, they want you flying around rather than in place.
It also makes total sense they'd be aiming for that attraction, it's a main "want" from the series, and the shelved VR attraction was to have us flying on broomsticks. The goal is the same, they just have to change up what ride system to use.
An while I wouldn't mind a flying theater attraction, I think that would be a fantastic addition to Isle of Berk which would make a great indoor family attraction.
