I have not been to Disney World since Magic Bands have been used. My question is.....I am planning on coming down for a quick trip in September or October just to go to a Halloween party. I am not planning on staying at a Disney resort and am not purchasing anyother park tickets except for the party tickets. Do I get magic bands? Do I have to buy them? If I don't buy them can I use any fastpasses or anything else? I do have a my disney experience account if that means anything. Thanks for the help.
