But just selling tickets i would more think you would get them at the guest services, like the small info kiosk.
But dont you show your ticket when you enter the station not the queue? Cause i always thought this guy was a bit misplaced in PC1, i feel he should be on the station gate, assigning rows, checking tickets, heights, etc.
When to show your ticket, I suppose, depends on how each park does it. Take Disney, for example. They don't have tickets, but they do have lightning lane passes, which are on your app. You must have your app scanned BEFORE you enter the queue. This would make sense with hard copy tickets as well. If you don't have a ticket when entering the queue, you'll be turned away when you reach the station, which would cause a lot of angry peeps, possibly having waited a long time in the queue, as well as disrupting ride boarding.
And yes, adding park tickets or ride tickets to the Info Kiosk would be an alternative to adding a new ticket booth kiosk.
Don't the queue greeters also signal when a ride is closed so peeps don't enter the queue line?
Yes. At well run parks... I once entered a queue for the Sky Cabin at Knott's Berry Farm, where there was an employee standing at the front of the queue, just to find out the ride was closed. It wasn't a popular attraction, so I didn't find it odd that there was no one else in line. But I chewed the guy out for not informing me it was closed. (I'm not insinuating Knott's is poorly run. It's really a great park, but they do occasionally slip up here and there)
