If you are staying on Disney property you call on 90 days before your check in date and you are able to make your ADR's for your entire vacation (if you are staying less than 10 days) on that one day. (=90+10 days )
If you are not staying on Disney property you can only make ADR's 90 days out so you would have to keep calling back every day. (90 with no +10)
For example
On property (90+10)
Call Monday and make adr's for Mon, Tues, Wed, Thursday, Fri. (up to 10 days out)
Off property (90 day)
Call Monday and make adr's for Mon
Call Tuesday and make adr's for Tues.
Call Wed and make adr's for Wed...etc.
