I made ADR's at 180 days out, hotel reservations 88 days out (I was waiting for a discount), and added DxDP at 50 days out. As you may have surmised, it doesn't matter if you have a hotel or dining plan when you book ADR's *unless* you want to book 180+10 out. If you're content with 180 days out, you don't have to have either, as I did.
