Ahoy, Carolan!
Thanks for cruising by the Moms Panel with your question!
You'll be happy to know that the onboard shops on the Disney Cruise ships sell several sets of Mickey Mouse ears that are cruise specific! My favorite ears were purchased last year on the Disney Dream. They are Minnie Mouse ears, and feature a big, red sparkly bow that's covered in tiny white anchors - just like Minnie wears on the ship!
I've also seen Mickey Ears with a tiny captain's hat, and several other styles to choose from. What fun to collect these awesome ears, that can only be purchased on the ships!
Shopping on the ships is one of my favorite activities. They have amazing merchandise to choose from! I always try to purchase a Christmas ornament each time we cruise, to remind us of the wonderful time we spent with Captain Mickey and his crew.
Hopefully you will find just the right pair of ears - wear them proudly! Have a magical day! - Diane W.
