I have been wondering how a queue could work for a Vortex replacement and I mocked up a sorta idea of a queue line with a double sided locker system and metal detectors (like Siren's Curse). The station of the coaster would be higher than usual allowing for a bunch of open space underneath the station that would be used for the double sided lockers, the exit gift shop, on ride photo booth, and a merged queue that would also feature a "pre-show" for the ride. The coaster model I have is a modern Vekoma launch.
