Personally, I don't want to be up at 7 AM on my vacation and I hate the idea of everything being so incredibly scheduled. Your points are valid, but there needs to be some balance between fastest finger and otherwise equitable. A requirement that you're in the park has been the best way to stagger guests and avoid the fastest finger component. I understand the sentiment / convenience side of things but the two ideals cannot exist simultaneously.
One thing that would absolutely be a huge step backwards would be a reversion to 3 advanced bookings. Until such time that the attraction count increases at EPCOT, DHS and DAK, those parks simply cannot handle 3 advanced bookings.
If there needs to be a hybrid of everything that also allows for simplification on a paid system:
- You can pay for Genie+ ahead of your visit
- You can make a single advanced booking per person per day that is unencumbered by what you do day of. Resort guests would have access to this at some arbitrary time ahead of their trip (say 7 AM, 7 days out + the length of their trip like the old 60+9 rules)
- Day of, you have your advanced booking + a rotating reservation that you can book upon checking into a park for the day.
- Once you've checked into a park for a day you can book reservations for other parks without having to be in those parks. You can also go back to your hotel or even leave property and book those reservations.
Those rules are essentially what is currently happening at Disneyland + an additional advanced reservation. The distinction of individual lightning lanes and tiers adds a layer of complexity that Disney executives don't care about because they're getting 6 figures + a day per attraction.
