Two simple words, given that I rather assertively declined a Magic Band on my most recent WDW visit, and found it both amusing and irritating that they mailed me one at home, nearly a week after I'd already left on that vacation (irritating because why can't Disney, or the cruise industry, get it through their thick heads that they are only hosting part of a vacation): Good Riddance.
Hmm. Looks like I'm not the only one here who finds Magic Bands to be stupid. The only thing I wear on my wrist is my watch (and maybe something made of Tyvek, to indicate that I've been admitted to a hospital, or to a convention, or to a museum, or to the Pleasure Island nightclubs that don't even exist any more). Speaking of Pleasure Island: the CM applying wristbands after they switched from gating PI to issuing wristbands asked me whether I was drinking (one wrist) or a designated driver (other wrist). In my case, the answer was "neither," since I'm a teetotaler, and my car was some 2176 miles away. Wish I'd had a chance to see "Samantha's Cabaret" a second time; of all the Library shows at Adventurers', it was by far my favorite.
I used to get designated driver wristbands when my friend and I would go to Giants games. It allowed me two free cups of hot cocoa.
