I've seen a lot people talking/complaining about families "hoarding" or having a stack of swaps. What I don't understand is why is this an issue? I can certainly see how this is an issue for Disney in that they can't control the lines as well, but why is it an issue for someone else? I think people just see the passes and automatically think, "That's not fair that they get that many." But my family many times would go ride headliners once in the morning with short lines, then go back later for the other parent to ride. So we would sometimes have 5 - 10 passes at a time. That in no way gives my family an advantage over another family. The passes were used for the parent who hadn't ridden yet. That's what the rider swap is. Not as extra passes.
If my family can only hold one pass at a time and only have a short time window to use it, we are put at a distinct disadvantage during those golden morning hours. Instead of being able to ride Splash Mountain with low wait and then going to Big Thunder with low wait (as families with no small children can do), we instead have to ride Splash twice in a row, which means Big Thunder lines will go up by the time we get there. Going to Disney with kids is already difficult enough, and now it will be even more difficult.
Of course this is not a huge issue, and we will adjust. I just find it disappointing that Disney is changing their system for the worse (in my opinion of course).
