There are people here who have admitted using the switch passes on subsequent trips, someone a few weeks ago in this forum suggested pretending that you forgot to ask at the beginning if the queue to get one at the end, even if you don't actually have a kid and there's someone in this thread who was planning to get one, even though their whole party was going to ride the first time. The bottom line, is Disney says to wait outside the attraction, meet up, hand the pass over, take over supervision of the children and board the attraction. If someone leaves the immediate area to use the bathroom, feed kids, etc and returns around the time the ride is over, that's one thing. But the person with the issue subsequently pulled additional FPs and rode another ride and got an additional switch added to their ticket, which means they tried to re-ride much later. And they're blaming Disney for not telling them that they can no longer use the system in a way that it wasn't intended to be used and is not described as how it works in Disney's official information. Abuse, misuse, loophole, all it means is, no problem here, as long as you follow the instructions, which they didn't.Some of us weren't "abusing" the system and couldn't sit and wait 45 minutes+ at Indiana Jones to "immediate swap" (haha) and had to leave to nurse a baby or put toddlers down for a nap while everyone else rode. That rider's pass was nice to come back later in the evening and have for the parent left behind to get to ride!
But yes, I'm know people abused the system also. But it is too bad for those in the above mentioned situations.
