Its business. Much smarter to allow the person spending $150 at your park (or more if they have booked a room) to have the edge on riding a key attraction rather than pandering to the folks who come 10-15 times per month with a monthly fee of $50 bucks
Because it's not isolated down to just A vs B. Otherwise, you'd never want to sell APs and you'd argue why did you bother selling them in the first place if I could just replace them with a full admission priced customer.
For the vast majority of passholders.. it was an UPSELL for Disney... and why they do it. They have to keep those customers buying as well.
If you let people queue up, it also helps promote multiple day visits as your guest would be paying a full day to spend a good portion in a queue for one attraction.
No, it just es people off and they are upset with you in what they got for their money. Disney has to maintain a balance of waits but also things people accomplish so they feel satisfied with their day.
No one goes 'thank god I wasted half my day in this line so I had a good reason to pay almost double to visit the park!'.
Disney wants waits to ensure people don't do everything to quickly.. but that doesn't make excessive waits enjoyable to guests, and so its not going to be enjoyable to Disney in the customer sat category.
Why on earth would I book a Disney vacation with hotel accommodations if it is likely we wouldn't get boarding passes?
Because no one is booking hotels purely for the idea of getting a BG? The same 'will I get to...' applies across the board. This is not blood sport to get a BG... just show up at park opening and you'll be fine. Oh wait, you're a hotel guest that means you don't have to get up nearly as early.. and you'll likely have multiple mornings to do it.
There's a reason WDW lets hotel guests book FP reservations months in advance
Yes, creating false value and other schemes to promote their resort bookings. Look, I understand the theory of using it as bait to drive higher revenue and higher margin customers... and that's certainly a valid case to evaluate... but that doesn't mean you munge things up or put on blinders to other business needs too.
Disneyland respects (and fears) their AP base... both local and remote. And they know that's because it drives that reliable revenue they love so much.
