This is an excellent write-up and I'm grateful for it.
However, since it was mentioned twice in the article and repeated by a forum user as part of the forum orthodoxy that FP+ is the cause of long lines, I'm going to go ahead and address this.
I've been to MK during those days of old in the Fall when it was 'dead' and, there was still FP+. And there weren't long lines on all the attractions. Why? Because it was dead. Except for the few headliners that always have a line, the FP line was no faster than the standby... because it was dead. FP+ didn't magically create backed-up lines, because there weren't enough people to fill backed-up lines.
Now, jump to a now typical day when the MK is getting twice the number of people it was designed for. Lines everywhere. And not because of FP, but because there's twice the number of people the park is designed for. The Peoplemover, which has no FP attached to it and has one of the highest throughputs of People per Hour winds up with an hour long wait. And that's because the park is past its tipping point.
You can sneer at spreadsheets,
@tirian, but that's data. It's information. You can't hold an opinion that ignores or runs counter to actual reality. The attractions can only throughput a limited number of people. That's a hard fact that can be represented in a spreadsheet. And if you have more people in the park wanting to go on those attractions, you've passed a tipping point and lines will form and grow longer and longer.
The lengthening of lines everywhere happened at the same time the attendance kept climbing and FP+ was introduced. I don't know why or how anyone would blame the lines on FP+ rather than on the obvious reason: A ton more people in the parks.
When Smuggler's Run lost its FP+ line, it wound up with the same hour-long waits at the other headliners in DHS. Why? More people in DHS than it was designed for (thanks to RotR and then MMRR). People were excited to see Smuggler's FP coming to an end and they proclaimed, "NOW we'll see what happens when you take away FP!!" Nothing happened except continued long lines. And yet, the blind faith and orthodoxy of the boards is that long lines are attributed to FP and not to... you know... huge and packed crowds.
The article mentions over and over how there's hardly anyone in the park, but then attributes no lines not to the lack of people, but to the lack of FP+. Meanwhile, the article is delighted there are no crowds and lines at the eateries, but attributes that to... lack of people. How does a low crowd become the reason there are no lines at the eateries, but it is not the reason there are no lines at the rides?
I know that FP isn't perfect in the way it distributes its 'cut the line' perk. But on crowded days, it just shifts people in the long lines, it doesn't cause long lines. This forum orthodoxy regarding FP+'s ability to create lines has no logic to it. But let's say it did... If there was FP+ enabled yesterday, who thinks we'd be seeing 30 minute or more lines at the majority of the attractions?
