As many have pointed out, a lot of this boils down to personal preference and touring style.
We love rope drop. We don't take afternoon breaks.
Comparing numbers between WDW and DLR is tricky. Because the FPs you get at DLR are for true headliners. The ones you get at WDW after the first 3 are often for secondary attractions that didn't previously need them.
The no reride thing just can't be overcome predictably for us at WDW. Because the things we want to reride do not predictably have FPs available for 4th and subsequent.
The tiering absolutely is about ride capacity at WDW. And I guess they're working on that. But I'm doubtful that anything I have seen in the works is going to change that. Much of what they do involves closing other things first. And when the new stuff opens, far more people will visit the parks than has been added in new capacity. So I think all the ride rationing techniques are here to stay.
I agree the time enforcement really sucked some of the fun out of legacy. But just as a matter of personal preference, I still will take it over FP+. For me, it comes down to wanting to keep that slate blank every day, and have all things still possible before I ever walk into the park.
No doubt any late start day will be better with FP+. Your down day sounds great. We just don't do down days.
Agreed that the onsite folks get a huge advantage at WDW. Everyone touts being able to schedule convenient times as a big advantage of FP+. But I see post after post from people trying to make the most of the only times that were available for this or that attraction. No doubt they are offsite or scheduled last minute.
Not sure that DLR will give any advantage to their onsite hotels thought. They really don't have to. And in spite of the fact that we stay onsite, I would prefer that they keep a hard line of needing to be in the park in order to schedule and then only same day. And even then I worry about people being able to spoof their location and game the system. The minute DLR lets people not in the park schedule FPs is the minute the whole thing gets out of control. Right now I'm still of a mind that this system might be ok, but a lot of it will depend on the details.
