I can just imagine how absolutely lovely your little Princesses are, Marjorie!
How exciting that they'll be on a magical voyage with Captain Mickey very soon. Princesses definitely need their Princess gowns. It is the most appropriate time to wear their costumes onboard the Disney Fantasy -- on Formal night, Semi-formal night and any night of your voyage. I think you'll need to plan for a piece of luggage just for their outfits :-).
I'm sure your little girls will love walking around the beautiful lobby atrium to meet their fellow Disney Princesses onboard. They will be ready for a photo anytime. On our previous voyages, we've had various run-ins with Princesses and Disney characters walking around the lobby - they'll even stop or send a friendly princess wave over to the kids. Make sure to check the daily Personal Navigator for
Character Greeting schedules onboard. When we sailed a few months ago, there were ticketed meet & greet sessions with Queen Elsa & Princess Anna as well as the Disney Princesses. If these are offered on your sailing, check the Personal Navigator and make sure you pick up tickets on embarkation day. If you are unsure, you can always stop by the Guest Services desk to ask.
And don't forget your Pirate costumes. The
Pirates IN the Caribbean Party will be such swashbuckling fun for everyone. I think you'll be taking a whole bunch of photos on this cruise... lots of magical moments to be made! Please let us know if you've got additional questions that we can help with, as you plan for your magical voyage.
Have a pixie-dusted day, Marjorie!
