But people are planning to use Genie+ on a given day and have some expectations/hopes (and maybe a written in pencil guideline) of what they are going to get with it. And if it doesn't turn out to get what they want, they have to on the fly come up with new "plans". I think it's easy to see how that can be stressful, especially given how little control one has when passes for on demand rides go quickly.
Here's the thing... if you are trying to make plans for things you have no control over or insight into the actual outcomes (What Genie+ reservations will be available, and when, if at all) and then stress about how they keep having to change -- These are self-inflicted problems.
You should have a strategy to steer your decisions... but if you are making future plans based on Genie+ reservations, of which you have no insight into, or even know when they will be in play... you're just hurting yourself. It's like running into a wall repeatedly and complaining your head hurts - Stop doing it.
If you make plans for future outcomes that are pretty much guaranteed to not hold up... and keep doing it.. I don't know what to tell you. Don't do that. This is still people trying to make the old model apply to the new.
Have a touring strategy that helps steer your choices. Take Genie+ reservations when they are available and fit your interests and opportunities. Don't try to plan on things you can't count on.
People have been so conditioned that you gotta have all these things laid out and in a schedule they can't function without one. Just have a touring strategy, know the key milestones you want to include/hit... then enjoy the park. Adapt to what is in front of you instead of forcing a timeline on everything. You really shouldn't have but 3 or so commitments in front of you... when you think you will be hungry, when your next booked reservation is, and if there is any other timed shows/entertainment you are trying to ensure you don't miss.
People got so hooked on the idea of optimizing wait times they've conditioned themselves to believe chasing commited times everywhere is best. It's like being oncall constantly.
No wonder lesser attractions are hurting in the parks - everyone is late, they're late, for a very important date! No time to say hello goodbye I'm late I'm late I'm late!
