ADR and dining plan question

[Nia20]

My mum and I are visiting in september we have the deluxe dining plan and staying onsite. I understand once our first booking date becomes available we'll be able to book the next 10 days? But how do I do this? And when will I be able to book the last few days of our 2 weeks?
Thanks for your help!

To take advantage of the 180 + 10 days you will need to link your resort reservation number in My Disney Experience. You will be able to make your arrival day dining reservations and reservations for the first 10 days of your vacation. The next day you will be able to one more day's reservations, the day after that one more day's reservations, etc. If you don't want to do the last few days one day at a time, you can wait until your departure day is within the +10 and make them all at once.
