ADR's at one time?

When I reach the 180-day mark to make ADR’s, will I be able to make reservations for every day of my trip, like Fastpass+? Or will I need to one day at a time, as I reach the exact 180-day mark?

If you are staying at a Disney property, then yes you can make all your reservations at 180 days. Now if you are having like a two week vacation, I believe you can only book up to 10 days. Also, if you are staying at a resort for 5 days and then switching to another one, you would only be able to make ADR’s for the 5 days.
