If they don't cap the number of
Genie+ sales the system will continue to be broken. Guest satisfaction with Genie+ is very low right now. Despite what you many think, Disney does consider guest satisfaction. But if they can sell half the amount of Genie+ and then double the price, it will result in the same revenue for them.
I do wonder if there are some "in between" methods Disney could use to assist with the way Genie+ works. For example, instead of being able to book at 7am for everyone - maybe the 7am time is for resort guests only and everyone else requires you to scan into the park. I understand Disney doesn't need an incentive for people to stay on property, but this would reduce the number of people booking a
lightning lane in the morning and maybe help things. There are some definite tweaks they could do to improve the system overall.
Remember Hollywood Studios used to have a tiering system for the rides? You could only pre-book 1 Tier 1 ride and 2 Tier 2 rides. They could do something like this with Genie+, especially for stacking (if you're holding a Tier 1, you can only stack a Tier 2 ride) - or they could even limit your Lightning Lanes for the day somehow. I know this wouldn't be preferable but it would make it more fair for everyone.
Personally for me, I prefer the old Fastpass+ system where you could book ahead of your trip, even if they started charging for it, but I doubt they go back to anything like that.
DLP's Premier Access Ultimate sounds good because it removes the scheduling aspect of it but I don't know if it would work in WDW?
I do hope the changes they make have a positive impact on Genie+.
