I realize all that...but with how crowded the parks are, and Disney not slowing down on marketing or cramming more people in...I really worry that it will get to that point. I considered us extremely lucky to get a FEA FP in a time-slot at least close to what we wanted on our October 2016 trip. We wouldn't have gotten it at all if I hadn't spent time multiple times throughout the morning checking availability. (Funny thing...we had FPs for the ride, but still ended up waiting more than 45 minutes. I could be mistaken, but it seemed like they weren't loading the boats with nearly as many people as they can hold.)
Generally, we stay at the values because our kids like them and we really don't stay in our room for anything other than sleeping/showering (with the exception of a "splurge" trip once in a while). We aren't usually repeat riders in a single day, with a few exceptions (GMR was a biggie, Grand Fiesta as well, and I'm sure the Mickey/Minnie Railway will be a favorite).
Sure, we can wait for a long time in a Stand-by line, but how many kids do you know can wait 2+ hours in line without needing to pee or getting hungry/angry/tired? Heck, I don't know many adults that can do that (and I think the violence another poster mentioned is evidence of this). I also was taken aback on our last trip by a FP line that was literally almost walk-on, but stand-by had more than an hour wait (I don't remember which attraction). Is there a "rule" for loading attractions with FP vs. stand-by riders? Even with a FP I would consider a 15-20 minute wait acceptable - especially if it meant shorter overall stand-by wait times for everyone. I guess my point is that no one should have to choose between paying an up-charge or spending 2+ hours standing in line for a single attraction, and I'd be curious to see how long the average guest (by average, I mean visits maybe once or twice in their life to bring their kids) wastes waiting in lines over a week-long trip. I'd also be curious to see how much time a repeat, knowledgeable visitor spends with their face in their phone monkeying with FPs so they can avoid the huge waits. Further, the "challenges" another poster mentioned are ridiculous and just illustrates the selfishness that has become pervasive in our society.
As an aside...I have 2 sons, both of whom have autism. In the past we've not needed to get the DAS pass because they are generally very good in line and we have strategies that help us all pass the time. However, with the way things are going, we will probably need to get one in the future because - and trust me on this - no one wants to listen to my youngest ask in a very loud voice if its our turn every 1.5 seconds for an hour or more, or worst-case-scenario have a melt-down.
