Kind of an evil genius plan, but I could see it being beneficial. Is it doable though??? The app would have to juggle a lot of different variables and as a basis for comparison MDE doesn't exactly inspire confidence lmao.
It seems more geared toward first timers and large groups who find the sheer number of parks, dining and attraction options, etc. overwhelming and need a little extra help planning out their day. I think it's a great idea assuming it actually functions as intended, which is a big IF. And I'd definitely like to give it a shot myself, but I'm probably not the target demo.
Not sure how this is going to affect FP+ but I personally wouldn't be sad to see it replaced with a cross between DLR's Max Pass and a (more affordable?) UO Express Pass. I think it would shorten wait times in the long term and wouldn't mind splurging (within reason) every once in a while if I'm visiting parks with family/friends and want to get a lot done.
Definitely theoretically doable but it would likely take extraordinary computer engineering and massive ongoing data processing.
All businesses are moving in the direction of capturing and utilizing the “big data.” (Think about Amazon giving you product recommendations... or Starbucks uses the big data to offer promotions as specific times and locations).
On the scale required for an operation like WDW, at the level I suggested... Likely to complex to get there tomorrow. Much like their initial FP+ and Magic band plans ultimately under delivered.
But I would expect to see that level of crowd management some day in the not-that-distant future.
