While at WDW during my Fourth of July trip,I went by Guest Relations and asked about the Fastpass policy.The Cast Member said that indeed the Fastpasses are only valid for the stated window.However,AT THE ATTRACTION CAST MEMBER'S DISCRETION,you MAY be allowed to use the Fastpass anytime that day after the beginning of the window and it is perfectly acceptable to do this if the Cast Member allows it.After I found this out,I used several Fastpasses long after the close of the window and was never denied admittance to the attraction.I didn't use a Soarin' Fastpass I got the first thing one morning until that night.There is always a chance the Cast Member will not accept a Fastpass outside of the window.It worked out great for me on my trip!
