Our last trip I went with a large group of extended family (15), and we had so many extra rider swap passes for 7DMT from the small kids who couldn't ride, that even after my wife and I had both gone, we had another left over. We were done for the day, though, so we just gave the RS pass to a random couple passing us by on our way out of the park.
Guess that makes me a Disney cheater and unethical based on what people say here.
I see your point; please try to see the other side. Other people waited in line to ride the ride. When you do something that puts someone else ahead of those people who are waiting, you are disregarding the fact that they have been waiting. You may not think it's a big deal, and others might not either, but all any of this gaming does is say to the rest of the guests that their time is less important than yours. Or in this case, that you get to decide who doesn't have to wait in a line.
it may not seem like a big deal, but in a place like Disney, we all have to accept certain premises. One of them is that we are all treated equally. That means we all get our limited number of fastpasses and when we don't have them, we all have to wait in lines. Any of these things that change that dynamic give the person getting them a benefit denied everyone else. Is that a big deal? No. But then some people say holding a place in line isn't a big deal. Some people say that letting the entire Micronesian Navy cut in from of you in line is not a big deal. Someone will always say getting an advantage is not a big deal.
And maybe it's not. But it's not wrong, or prudish if someone thinks it is. It's not the morality police to suggest that maybe you ought to think before just assuming that gaining -- or handing out -- an advantage to someone else is a good thing.
The other thing apparent thing about rider swap is that sooner or later WDW will stop it. It'll be tied to bands and this kind of thing will be limited. The more often it is used in ways other than it's intended -- which is to give a parent who waited in line the chance to ride despite the chance they have an child too young to participate -- the quicker that change will come.
