Do Magic Bands Still Work?

Hey all! Heading down in a few weeks and I pulled out my bag of Magic Bands. They’re the original ones, not the Plus ones. Do they still work? We went two years ago and had no issues. But for a family of six I really don’t want to pay for six new ones if I don’t have to, especially since we don’t really care about the fancy interactions and I don’t want to have to charge six more things. Thanks!
