I didn't know I needed to watch this but it very much mirrors my thoughts on the original FP system compared to FP+ compared to the monster that is Genie.
Here's my thoughts: So as Cast and Guests have been saying for years, we need to go back to the original Attraction based point of distribution Fast Pass system. Perhaps not with paper tickets but at least only with same day, same park access so the "monster" provides more equal opportunity without getting overwhelmed. Heck with a digital system you could scan a geo locked QR code for an attraction and then still be able to cancel it from your phone anywhere in the park to be able to reserve a different attraction and if your entire party is assigned to the same app, then there wouldn't be the issue of getting multiple time slots like the old paper FP system was prone to do for larger families. The ability to cancel then gives Disney the opportunity to redistribute those FP or "throw them away". Additionally Disney would still maintain the ability to inform guests of ride closures and offer alternatives like FP+ did. It would also provide Disney the ability to limit or turn off access to an attractions FP reservations if for example they want to slow distribution. Something like (no more FP are available for distribution until 2pm, would you like to be reminded when more are available? (with an in app reservation slot so they don't have to run back to the attraction)) This would be particularly handy when a standby line is long or an attraction is prone to break down and needs the extra time to catch up.
Essentially it would be a hybrid of the original paper fastpass system (you have to go to the ride to get the pass) and the digital component of being able to cancel and be notified of the Digital Fastpass+ system.
