I was there Presidents weekend, which is compared to a Spring Break Week and with the new +FastPass System, WDW lets the FastPass people on the ride and hardly any standby.
A 30 minute wait for Peter Pan, I thought why not. 90 minutes later and still not on the ride, I realized standby for any ride is a stand still, while watching +FPP people walk up and walk up and walk up and get right on the ride.. The CM would actually watch people walk up the ramp, vs. turning around and letting 10 people on the ride from the stand by line. He only allowed standby people on the ride, if absolutely no one was walking up the FP ramp. I realized Disney is trying to please FPP people.
Sorry for turning this into a FPP story, but this is the reason for longer than average standby lines.
