Ya know I have to wonder now... Yes locals would get screwed but presumably your already getting the FL resident discounts and have a AP as well so you would just come back another day when its less crowded. I see this as a low cost perk to staying in park... like the good old days when you got your Ultimate Park hopper free with your room. When they broke the tickets out with the Magic our way not yours plans the effectively doubled the cost of the trip, result was we cut back our visits by half.
The economics from Disney's POV is simple, small up front fee to change the Fastpass system, Sell out all your higher priced deluxe resort rooms and shift visitors to choose a higher priced resort, spending more than they normally would and draw more people on property where we own everything and can milk every last penny from them rather than loose money to the hotels on the outskirts of the property. There is a very low up front cost, high rate of return, in their excel spreadsheet bottom line cost benefits rule world its a slam dunk.
In reality, repeat customers (the Disney loyalist) will be forced to cut back the number of visits to get the same "Disney Experience" they are accustomed to or will just say to heck with it and do something else for vacations. New customers who do not shell out for the deluxe accommodation's on site will not feel the magic and will probably not return. Locals will probably just switch allegiances to a new park if things get too bad.
Depending on how big the shifts are it could potentially hurt Disney long term but give them a huge gain for say 4-5 quarters. A lot of companies are only focused on 1-2 quarters out these days so the bean counters will love it. I sure hope it never happens though.
As for AP holders, I doubt it only because they are loosing so much money at the gate for AP users as it is, but I could be wrong there... I believe you get a discount on hotels as a AP holder so they may just figure you all will stay on site to get the perks like the rest of us.
The real question is if you turn on the waterworks and cry about your room to get the suite like Queenie did do you get the added perks of that room?
