So I'll outdate myself a bit that I remember when magic bands were free (2019 was my last visit as an AP holder).....I have an upcoming trip and these Key to the world cards. I see it can open up my room door and let me into the park and make charges....but making charges? If we are two different parties, so like my aunt and I go can we make separate charges to the cards like we could magic bands? (or at least what I remembered we could do.)
