I agree with most everything you had to say. BUT… Your two points i snipped below contradict or conflict.
The first point is not a fair comparision - It is NOT because more people are feeling comfortable to travel that I get on fewer rides at Thanksgiving 2021 using G+/ILL than I did with using Fastpass+ during spring break 2019. Pretty equivalent crowds. Your second point is ONE of many reasons I get on fewer rides now with G+ /ILL versus using FP+
The system also has more glitches when using it - especially with those crowds noted above - and no functionality to modify a ride and rebook smoothly. It is harder to plan our day in real time when doing the G+ times “on the fly” around preplanned ADRs and experiences with no ability to select times for a
lightning lane with
Genie+ meanwhile specific times selected for ILL’s cannot be modified.
So on your first point below - it is EXACTLY an issue with G+
One sort of throws their hands up and gives up or buries the head in the phone “Fiddle-faddling“ as Molly calls it rather than going about a plan that was sorted out previously with time for breaks and pauses and surprises.
Im sure somebody else could talk about how the waits have changed or not changed that I couldn’t speak to. I just know my experience was worse and cost more than before G+ and for that I am pretty darn annoyed and disappointed.
