Here's what I do to make it easier, although I know not everyone loves this level of planning, but I enjoy it...take it for what it's worth:
Well in advance of the ADR and/or FP+ selection window, I create a calendar of our day to day schedule (I use excel) to show which parks I plan to attend on what days. I break it down by breakfast, am park, lunch, pm park, dinner, emh and late night. I use the crowd calendar info from
UT to help determine my method. Obviously not all of these blocks are filled in with activities (although some say "sleep in" or "pool time" to build in breaks).
When ADR's are avail, I book them based on my park schedule and input on my calendar.
When FP+'s are avail, I book them based on my park and ADR schedule--this isn't as hard as you may think, and it's way easier if you print your calendar to have in front of you while you book your FP's.
You can TOTALLY switch things around and maneuver to make them work for your plan/ADR schedule. That said, on first pass, you may need to just accept what the system is giving you, but then you can go back in and change the times to better suit your schedule.
