But! it is a mathematical possibility.
And those three rides are FP lines. So let's say that 25% of the guests skipped the rides in the past. But now that population is popping in for three quick FP rides throughout the day - because they don't want to waste their fp+.
Those three quick rides will add volume and slow down the standby.
I saw it happen with my travel group in October. The people in my group, who never rode rides, would not waste a scheduled fastpass time.
And for the most part everyone was thrilled they took the time to ride. The wait wasn't long and they chose mild rides.
We used ours for star tours, maelstrom, little mermaid, dinosaur, tough to be a bug, etc. we made all of our appointments. These are not rides that typically need the FP, and we probably would have skipped, but we jumped in. It didn't keep us out of the restaurants or bars or stores or FW kiosks, because we only rode three rides.
Combine that with all the stories of people who finally get to ride the headliners because of FP+. All those people who simply skipped TSMM, soarin, Safari, space mountain, RnRC, and splash are now grabbing ride capacity slots that was out of reach before.
So overall, I think ride demand is skyrocketing now, and lines will increase across the boards.
