Actually the only people "dictating other people's vacations" are the ones who create wait times longer than should be by saving their fast-passes for peak times.
Yes, when many people save their fast passes to use them at peak times, the ACTUAL wait time for the standby line will be longer than what is posted on the entry to the ride. *THIS* could cause people to wet their pants, miss their ADR's etc....all beyond their own control.
people get *GET* the fast passes CAN control whether their bathroom times and ADR's. When you purposely disregard the wait it's supposed to be done so that you can "enjoy your vacation", you are actually negatively affecting other people's vacation.
And that...is selfish
(and un-disney like)
(and immoral)
(and pathetic)
