The trouble with Sky Voyager is that it loads on two levels, so you have to split the ride group into two in pre-load, and that is the best time to do the safety video. I think Tokyo's version of Soarin does it best - a short pre-show that has nothing to do with safety in one room, then mustering everyone to their boarding groups for the safety briefing in a different room. With each room taking a few minutes, plus the travel time between rooms, it eats the ride time well, so you don't feel like you're queueing for that period. Doing it for Sky Voyager would require additional queue staff to group earlier in the line, and it would see the bulk of waiting guests pushed into the outside overflow queue to utilise the inner rooms as pre-shows. I'd love to see them change it up but ultimately I don't have a problem with the way it is currently set up - It's a nice place to go for some respite from the heat and spend a few minutes in the air conditioning. I have queued in the 'departure board' room a few times (outside the luggage room), but no way i'd wait in the overflow, no matter how much I wanted to ride it. So I guess for most people who aren't dead-set against anything the park does, it's fine how it is.
