TBH, I don't know that that would have bothered me. What I like about legacy is that each day was a new day, and I was *guaranteed* to get a FP if I showed up at Rope Drop. When that FP would be wasn't under my control, obviously, but we always managed that without huge changes to how we tour.
What I dislike about FP+ is the amount of preplanning necessary, and that even though I was online at 60 days at midnight, that I was shut out of FP+ for certain attractions simply because my trip is too short (4 days) and people whose windows opened before mine were able to take all the slots.
Under legacy we toured how we wanted and fit FP in as we desired, based on the situation we were experiencing in the parks that day (crowd/weather/etc). With FP+, it feels like the opposite...that I'm planning how we'll tour around the FP+...with the downside of not knowing what crowds will be like,what weather will be like, etc..
I'm withholding total judgment til our trip...maybe FP+ will work great in the park. But even if it does, I njust don't like this level of planning beforehand. It just isn't fun for me. ADRs were fun...what this was just wasn't.
