We usually look at the restaurants and write a list of which ones we like . Everyone likes different we like be our guests for lunch garden grill in epcot for breakfast ohanas for evening meal. Once we have picked which ones we fancy we do a rough day plan using busy day guides then once we know which parks doing what day we know which ADR we need for that day. As if we were doing epcot that morning we booked garden grill for breakfast.
We just did Disney 2 days on our trip this year so didnt make any ADR in advance but on the day when went on to APP to book most had last minute availability on the day.
If you book any now then decided later on you want to change as long as you cancel more than 24 hours before you wont be charged.
The ADR were easy to make using the Disney APP we just made sure to book the ones we really wanted first which was be our guest and Ohahans as they tended to be hardest.
Did you have to give the agents a list of what you wanted or was you letting them pick for you?
