Wait, so Disney implements a major software change, totally revamping the line skipping structure across its parks. They do so coming on the heals of the largest disruption in travel/attendance in the lifetime of the parks, and do so with limited to no beta testing. In fact they open up the system prior to international travel being fully re-opened further scewing the intial data. They do so in the last quarter of 21, and you somehow thinking waiting until they have some actual data to show how the system is working is refusing to do anything? I mean seriously the system has been in use for basically half a year. They haven't even gotten a full summer season of data to see how it is functioning, to see where there may be areas to improve it, and then implement those changes. And lets be honest parks are packed, attendance isn't suffering, and it doesn't appear future reservations are tanking. This isn't a life and safety issue that requires a snap decision, nor does it appear to be having large scale impacts to sales.
You need hard data, and a sample size large enough to be meaningful to see how the system is functioning, and you don't get that from message board complaints from Veruca Salt wanna be's screaming to change it "NOW NOW NOW." You need some time to see what the system gets right, and what it doesn't. There is no need to rush that process. And if/when changes are made which may effect previously sold product, you need to time to either phase in changeover or figure out a refund policy. Again all things that take time.
