imagine this.. the entire queue station enclosed... the only thing you can set besides 'queue' is the occasional TTA Traveler gliding by.. Seeing the TTA go by adds to the sense that this is a 'Space Port', not just some sterile space shuttle launch facility... basically a 'space airport'.... Same lines as star tours, I guess.....
As the coaster trains arrive, the airgates (themed to 'airlocks')open, dispensing a quick burst of 'steam', with a rush of air.. a recorded voice tells you it's time to board your shuttle to depart.. you get in, strap up (harness down) and and the flight crew comes by to do a quick 'pre flight check' (harness check).... after which, the doors close, with a slight 'squeal' and 'vacuum' sound to signify the 'sealing' of the airlocks, and the show starts....
sounds like a lot for a coaster station, but if done right, it would be seamless and could all happen in seconds....
