Ahoy, Paul! Welcome to planDisney, and thank you for your question.
There used to be an old television commercial about membership having its privileges, and that saying is certainly true with
Disney Cruise Line. Once you've completed your first sailing on a
Disney ship, you are automatically enrolled in the
Castaway Club, Disney Cruise Line's loyalty program.
There are some awesome benefits to being a member of the Castaway Club, and as a Silver Castaway Club member, you can indeed book new itineraries one day sooner than the general public. The beautiful
Disney Wonder will be setting sail on those new Australian and New Zealand itineraries next fall, and you will be able to book one day before the general public can begin booking. Expect these itineraries to begin booking in the next few weeks.
I hope you get to take advantage of these "local" departure ports, Paul! I'm expecting these to be some brilliant and popular new Disney Cruise Line adventures.
Anna
