Hi Elizabeth,
Thank you so much for visiting the Disney Parks Moms Panel with your question. A vacation at
Aulani, a Disney Resort & Spa, sounds amazing, and even more special to book it for your daughter's birthday!
If you are a Disney Vacation Club member looking to book this vacation using vacation points, you will be able to do so at 11 months ahead if Aulani, a Disney Resort & Spa is your home resort, and at seven months ahead if it is not your home resort. For booking a vacation in August 2017, this works out to September 2016 if Aulani, a Disney Resort & Spa if your home resort, and January 2017 if it is not. You can book online at the
Disney Vacation Club website, or you can call Disney Vacation Club Member Services to help you with this reservation at 1-800-800-9800.
If you are not a Disney Vacation Club member and are looking to book your stay at Aulani, a Disney Resort & Spa using a traditional payment method such as a credit card, you can do so by calling 1-866-443-4763. I called and spoke with a cast member there today who let me know that currently, they can book vacations until the end of 2016. She let me know that bookings for 2017 should open up sometime in late August or early September of 2016. I suggest that you call them periodically as that time approaches to see when booking for 2017 becomes available.
I hope that this information is helpful for you, Elizabeth! Have a great time planning your magical vacation, and please do let us know if you have any further questions.
