This is not super hard:
7 Day lead time to book ILL and first Genie+. Keep the window open until your park day. If people get ToT at 3 pm (instead of their desired Slinky), at least they have time to plan the rest of their day. And it keeps them tucked in at 7 am during their actual vacation.
They are clearly not going in this direction with the changes that are coming, although I think the June change is a good one with potentially limiting Genie+ distribution.
Disney kind of put themselves in the corner a bit. They used "Tiers" to help balance out FP+ supply and demand. Now I'm guessing nobody is throwing LL out for shows anymore. This is actually making Disney have less functional FP/LL inventory. And if they reintroduce the Tiers, it makes Genie+ not worth any upcharge money. Nobody wants to pay Genie+ for a better or guaranteed seat.
Anyone remember scanning into DHS to hit Pixar 3D and Figment, to get the rolling going for better FP+?
