Oh I would not bet on the 'easy to get' part, This system will be tweaked to allow only the most profitable guests to gain entry at peak times. Say 4'th of july at MK. AP at All Stars BZZT no park for you, First time foreign traveller at GF, Let's roll out the red carpet for you. Big data will be used to choose the guests who get into the parks and with dynamic staffing kiss the discounts and '
free dining' buh bye.
At non-peak time that AP holder at All Stars might be able to score a MK or DHS reservation unless of course they have a time reserved at Savi's or CRT then they will grudgingly be allowed to enter. Just wait till ADR's are tied to park reservations you need a park reservation to make a ADR.
Even at non-peak times it may be more profitable to turn people away than to staff up to handle more people.
Being a corporate weasel myself it's not hard to come up with these scenarios because we've wargamed them all, not at WDW but in other corporate contexts. Pro Tip it's getting more important to fill out those warranty cards because they tell corporate you have spent money,
