@Dwarful I agree that the kiosks at the restrooms at the juncture between Adventureland and Frontierland were easily the most crowded. I think they were just the most visible. Great opportunity to remind ourselves to check the maps... the kiosk in front of Jungle Cruise wasn't far from there at all and never got that busy.
As far as the complaint I'm seeing on various threads about CM's not letting guests do the kiosk thing themselves (not directing this at you, just making a general comment here)... I had a different experience on that one. I did get to touch the screen at the kiosk in that very spot in front of those restrooms, and I immediately felt the need to go scrub my hands down... and I am NOT a germophobe! That screen had some kind of gunk on it that made it difficult for the screen to sense my touch. They really should have shut that one station down long enough to clean that crap off... but instead, the CM came over when he saw the screen wasn't working for me, saw how gunked up it was, and told me to use my fingernail. That worked better, but it was a bit unsettling that he didn't seem to be too embarrassed about how dirty that screen was lol.
So, ever since our first night, I had no qualms letting CM's touch their own screens. Cuts down on germs being transferred, and for most people (not us who have played with the system since January, but the people who don't know much about the system) it actually probably makes the line move more quickly to have someone working the passes who knows what they're doing. Sure, it's an annoyance for people who DO know what they're doing, but Disney has no way to differentiate between the two, so IMO it's easier for them to streamline it for everyone and keep the lines moving.
