We just got back last week and I did see Minnie ears. If I am not mistaken they were not like the regular ears but attached to a headband.Not sure about the cost since I have two boys.
we got ours at DTD. Take the receipt to MK and they will personalize it for free.I can't remember the name of the store but any CM can tell you. The CM that sold me the hats told me about it. Also they have the hats in infant sizes too.They are not sold w/ the others. They are in the infant clothes.My favorite picture from WDW is of my kids (DS9,DS7,DD6,DD1)wearing the hats.
Thanks. I'm not sure which way we'll go with the ears. Head band or hat. I don't know if my DD2 will wear a headband. I guess we'll just have to see both styles and try them on.
