It is a perfect example of different approaches for different properties:
- California = MaxPass - high number of local attendees, lower cost option, digital, day of
- Tokyo = Free FastPass - high number of local attendees, free option, day of with limited exceptions for resort guests, day of, some attractions are virtual queue & lottery based like RotR
- Shanghai and Paris = Disney Premier Access - mix of local and tourist, smaller number of attractions, pay to ride system, with some option for virtual queue at least in Paris
- WDW - This is purely speculation from a program/execution perspective. But it draws mainly a tourist audience, has the most attractions of any Disney resort worldwide. Any system likely benefits “loyal” or onsite guests and offers fewer advantages for offsite or day guests. I’d wager a hybrid of free and pay, possible pre-booking for resort, but day of for offsite/day guests
