On Monday, my dh and dd were going through the fast pass lane for Splash Mountain and someone in the stand-by line said "Wow, looks like fast pass is the way to go." My husband stopped to talk with him and it turns out that the guy in the stand-by line was under the impression that only Disney Resort guests could use it. Does Disney give information about Fast Pass out when they sell tickets to day guests so that they know they can use it? Seems like a lot of people are waiting in long lines because they don't realize they don't have to!
