Hi there, Kimberly!
What a great family vacation! I hope your time at
Aulani - a Disney Resort and Spa is filled with magical moments that become some of your favorite family memories.
I want to start by saying that you will not be lacking in
Aulani activities, even if you don't book excursions ahead of time. However, there is always a chance that some things will be more difficult to book the closer you get, so you may want to take a look at the list of
excursions now, and book in advance the things you would be sad not to be able to do. I know that the surfing excursions are quite popular, as is the trip to Pearl Harbor.
Other things you may want to consider in advance is making
dining reservations and activity reservations at
Aunty's Beach House. You can
pre-register children for Aunty's Beach House, and add on activities as you'd like.
Wishing you an absolutely magical vacation!
Anna
