Hey there, Hi there, Ho there, Linda!
You're as welcome as can be here at the Disney Parks Moms Panel, so thanks for your great question. I love how eager you are to "get your ears on!"
Disney Parks are always releasing such adorable themed Mickey Mouse ear headbands, clothing, Spirit Jersey, purses, and accessories. My current "wish list" for some of these is very long! Recently, as you mentioned, some Little Mermaid-inspired Ariel ear headbands were spotted in the parks, and from what I hear, they sold out pretty quickly. I have a feeling that these will be in stock again soon in the parks. We have seen similar patterns happen with other popular designs such as the Rose Gold ears, for example. I would also keep checking the
shopDisney.com website. Usually I have seen items appear in the parks first before making their way to this site, so hopefully they will pop up soon.
If you are going on a Walt Disney World Resort vacation in the near future, you'll definitely want to stop by
World of Disney in Disney Springs. This store offers the largest selection of Disney items in the entire Resort as well as your best chance of finding these cute ears and as well as some other whozits and whatzits.
I hope this helps, and see ya real soon!
