Yes, we all do have a way of showing, and vociferously defending, our biases!
You make a decent point that, as the thread you've linked proves, there are a variety of people who are unhappy for a bunch of different reasons. Despite my bias for, I have always acknowledged that FP+ has warts. It's shortcomings definitely include locals and off-site trips planned on short notice. CMs visiting the parks have the same challenge. The system doesn't always work as intended. Disney changes hours and schedules, messing up people's planning. Standby lines for some, even many, attractions are longer. Multiples rides on headliners, especially in parks with tiering, is more difficult than it used to be. Yes, we even ride fewer attractions per trip than we used to because, even though we ride everything, it is harder to get multiple rides per attraction in. But for every wart I can come up with a positive takeaway.
Sometimes I feel that is what is missing when a lot of people express their biases......the consideration of all sides of the issue. I have a bias for, and all things considered I think things are better for us, but I come to that conclusion recognizing that there is both good and bad, and that the good and bad effects different people in different ways.
The whole of my posting on the subject over the last year would clearly say 'the system has its flaws and may not work for everybody, but on the whole, particularly for my family, I think the system is a positive, and a trip to WDW can be as great as it ever was'.
On the flip side, all I kind of take away from some other people's posting is that the system is without a doubt 'absolutely lousy, as you will only be able to enjoys 3 attractions a day while the balance of your time in the parks will be fraught with soul crushing boredom and trip killing disappointment'. That may very well be true for those who can't be flexible or are unwilling to adapt, but isn't there room for even those people to be able to say.......'sure, the system has some things that really do work, even though on the whole it doesn't work for us'?
I completely agreed with your post until you said the bolded. I haven't read any post that mentions "Soul crushing boredom" Please provide your source.
I am saddened with the direction Disney is going with the theme parks. Frankly. I don't know if I will be able to lower my expectations enough to continue visiting WDW, but this is for me and my experience.
But please don't dismiss my opinions as simply being an unwillingness to adapt. This is a condescending statement. It would be comparable to me telling you that the only reason you like FP+ is because you "think Disney can do no wrong".
