No offense to the original poster of this topic, however this topic is inane, stupid, and pointless and looking to start another argument amongs the posters (similar to the refilable mug debate). Using a pass after the allotted time does not defeat the system of Fastpass nor does it mess with the timing of the queue. A delay in using your fastpass just means that one more person will go through the standby line faster, thus, NOT creating a delay or "stealing" time from anybody. In fact, delaying the use of your fastpass just means that there's a better chance that fastpass will be utilized during a "slower" time in the day and creating a natural optimization in the queue system (being that the busiest time in the parks is generally midday..and most people put off using their fastpasses until later in the afternoon/night).
