The app does not work as a vacation planning tool at all.
The app barely functions as an in-park/day of aid due to far too many (and unnecessary) Disney non-park advertisements that clutter up the home page.
Imagine if the home page of the app had the map function (With wait times or dining) available on the first screen you see. Wouldn't that be more helpful than all those advertisements? Wouldn't that be a better user experience? Or, if you are an on-site guest, what if the home screen showed your plans right there on the first page you see? Wouldn't that be something?
Instead we get a Health Acknowledgment, the a listed of user experiences that have changed (including the stuff in the Health Acknowledgment), A link to Disney social media and a button to buy Photopass,a countdown clock for the 50th that has been at zero days for 4.5 months, Ride ads, videos of stuff inside the park that I should be experiencing in person, videos, more ads for stuff, ads to get to Disney Springs,Ads for shows in Disney Springs, Ads for MMRR, Trivia ads, Links to other people's social media about their Disney vacation, Ads for Disney+ and finally an ad that takes you out of. the app and into the Disney store.
All of that is just garbage user experience. It is an in-park aid. Not a place for 16 different online webpages that are not helping me navigate the parks or vacation.
