Personally, I think the whole complaint boils down to this ... "I can't ride __________ 3 or 4 times a day like I used to, and the standby lines are a little longer for my other favorites"
Thus far nobody's been honest enough to actually say that, but I believe that statement boils the issue down to its core issues.
I've said this many times. This is precisely the issue. FP- was a "hidden gem" in that if you knew it well, you could manipulate it to get on way way way more than the average guest. You could pull tickets early, pocket them, save them up for later, there was a whole strategy to it. All at once, that is gone.
I've made the analogy of an ATM where you go up every morning and find that a bank happens to spit out a $5 bill at the same time. You use it for years, picking up your $5 a day, nobody ever knows, only the bank loses money. (even tho really, all the other bank customers are losing as a result). Then one day, the bank fixes it, and you're MAD at the bank for fixing their ATM which previously only benefitted you. Now all of a sudden your secret edge is gone, and you are just like everyone else. That's what FP+ did to those who used to know FP-. I get that, and believe me I felt the change as much as anyone!
But the case LakeTravis has asserted, is that now under FP+, a WDW vacation is reduced to riding 3 rides via FP+ and then everything else via long slow lines.
And that is just not the case. Tho that may have been his experience, that was by his choice, not a force of his hand by Disney / FP+. I and many others have demonstrated that with a little re-thinking of ones plan, you can get pretty much as much value out of FP+ as you did out of FP-. And I have done that on my trips. On a given day at HS on a SWW day, we rode (seriously) TSMM x2, RR x2, TOT, Star Tours x4 (approx), GMR, saw Dis Jr LOS, met Buzz and several Star Wars characters, PLUS made both opening and closing ceremonies, plus used our RD time to register for JTA, plus had a Galactic Breakfast. That is one heck of a day to conclude that as a result of FP+, one is limited to 3 and done. It is just not the case. I would just like if LakeTravis acknowledges that FP+ does not cause such abysmal vacations just because his was so.
