I think this is what’s behind the Genie system. Basically, the app will plan out your trip itinerary for you (Park reservations, ADRs, Fastpass, etc.) based on your preferences but also to balance out crowds.
If your itinerary has you scheduled for ADRs at Be Our Guest but your party changes it’s minds and wants eat at the resort, Genie will show you what’s available (this is not too different than what people currently do, but manually by hunting through options on MDE. But imagine Genie showing special last minute offers to entice your party to give up your ADR for BoG in favor of a 20% discount somewhere else? The dynamic adjustments would make you feel like you have legitimate options.
If it works correctly (and that’s a HUGE “if”), trips will feel much more casual than they currently do.
