I know this is has been said multiple times but I think it’s still relevant to this current conversation, what would be the logic from their perspective in Disney reverting to a system that costs the exact same as the previous one, but instead takes on more attributes of an older system, making it a lesser system? To me that makes absolutely no sense. The various better options that have been proposed here are certainly not unique or groundbreaking in the sense that Disney couldn’t or wouldn’t have come up with them on their own and possibly considered them or aspects from them. That they went to the prebooked 3 over all other options tells me they have reason to believe it was in fact the better system overall for the groups they are targeting as consumers of LLMP and LLSP. Like many have pointed out, the obvious shift to a prebooked system from Genie+ would have been simply allow that first attractions to be booked ahead of time but otherwise nothing changes. They instead completely upended the whole thing and went with not only 3 but a scheduled 3. I think the choose your own times aspect is likely also something they found was an important aspect to keeping people happy aka spending.
I think it’s even further supported that at WDW the system is the way it is by design and not by incompetence by the way DLR and WDW have distinctly different systems, with DLR being much friendlier to short visits and unplanned/flexible guests. I think this reflects the difference in the make up of guests on the two coasts and how people visit the two resorts.
Disliking this new system is (obviously) a valid take, as is discussing how it could be different and better in one persons opinion. I just don’t think they fell into the version they have at WDW by accident, I think they have reason to believe the 3 attractions in advance on one’s own schedule - despite how some seasoned guests may feel about the quality of the 3 - is key when it comes to encouraging advance purchases and even on-site resort bookings.
