Ahoy, Catherine!
Welcome to the Disney Parks Moms Panel and thanks for logging in a question. Your little Princess has Royal duties when onboard Disney Cruise Line, and she cannot disappoint the rest of the Princesses. They must all meet, take pictures and exchange warm hugs.
The schedule for the Princess meet & greet sessions are subject to change and may not usually be available until embarkation day. These are ticketed events and you must request your ticket from the Guest Services desk onboard. There may be more than 1 scheduled meet & greet, but Guest Services will be able to confirm this if it fits your schedule as well. These are free events, but you'll need to have a ticket once you arrive at the short queue. You'll only need 1 ticket per stateroom.
I suggest booking your ideal time now, so that you've got a spot in the books. Once you are onboard, check the ticket schedules and head over to
Bibbidi Bobbidi Boutique to make any changes if you need to. One of the Fairy GodMothers In-Training will be able to help you out.
Wishing a wonderful voyage as you do
Disney differently onboard Disney Cruise Line, Catherine! Please do let us know if you have any additional questions that we can help with.
Enjoy!
