It gets a little confusing when you start talking ADR's.

You can call Disney Dining to book your ADR's 180 days from the day you are to check in. If you are staying at a Disney owned resort ( or "on property" as most people call it) then when you call 180 days out from your check in date you will be allowed to go ahead and book up to the first ten days of your vacations ADR's.That is were most people get confused, it took me awhile to get it all figured out myself.

Then to book the rest of your ADR's for the remaining 11 days you would have to call back each day to book the next day and so on. I have never booked ADR's for more than 11 days so someone else might have better advice on that part.
