You can’t see all of the return times listed in one window (the way they appear in the 2nd post on this thread) unless you’re in the park. As mentioned by a PP, you can click on the ride on the app, and it will show you the current FP return time. So right now, I’m not at the parks, but I can see that “It’s a Small World” is distributing FPs for 7:05-8:05pm.
How many days will you be there? Parkhoppers or not?
If you have the time and don’t need to crazy-maximize your FP efficiency, it’s not that difficult to bunch FPs together by location. For
Disneyland, you’d want to start with Tomorrowland book Space, Star Tours, and Buzz, then hit Matterhorn, IASW, and Roger Rabbit, then hit Big Thunder, Haunted Mansion, and maybe Splash. Now, this would be a very full day of touring, and it would leave out Indiana Jones and maybe Splash, so unless you hit a cancellation on those, you’d have to pick them up on another day... but it’s perfectly doable to book them in a certain location order if you prefer.
DCA is tougher, but still doable.
