Are you there now?
If you are, you can just show the GAC to CMs at the attraction you want to go on. That is the general instruction on what to do with the GAC at attractions. Whatever icon is on your card tells the CM in general what sort of assistance you need.
Not all attractions have all things people might need according to the stamp on their GAC.
So, at one attraction, you may be routed one way and at another attraction, they may not have that same thing. So, CMs at the next attraction may have you do something else.
And, there may be several ways to handle the same need. So, it's possible one time you come to an attraction, the CMs may have you do one thing and the next time they may have you do something else. It doesn't mean either CM did things 'wrong' - it could just mean that they thing they did one time was not available the next time.
I realize this doesn't really tell you exactly what you are asking, but it really is not possible to tell anyone that exactly.
