We tired of tracking down ADRs early in the game and switched to having most of our meals at Disney Springs using Open Table to book. Our traveling kids were past the age where character meals were wanted which simplified matters.
This freed us up to narrow down the park and resort eateries we wanted and just concentrate on booking them.
You can also use various reservation finders like “mouse dining”. Easy to find via Google; most aren’t free anymore but the price is small for something you may really want.
Have fun.
