The ironic thing is that I literally have no use for a Magic Band because they got rid of Maspass. I don't buy
Genie+, don't stay on site and mostly mobile order. If they still had annual Maxpass or free Fastpass, I could see a potential benefit of Magic Bands in that I wouldn't have to fiddle around with a phone each time I wanted to use a Fastpass.
If they added photopass to Magic Keys, I may also see a minor benefit to the Magic Bands if I could just tap for attraction photos rather than enter the code. So Disney will have to add annual Genie+ before someone like me would even consider buying a Magic Band.
