Disney Treasure's October 10 Sailing Tests Key to the World Wristbands for Guests Without DisneyBand+
If you are sailing Disney Treasure from Port Canaveral on October 10, expect a wristband at check-in unless you already own a DisneyBand+, which will simply be activated. Because rooms need a card to power the lights and air conditioning, ask the line before you sail how that will work. Ask too whether you can opt out or request a standard card, since Disney has not said. Plan to drop your wristband in the containers outside the terminal on October 17, and do not count on using it anywhere else.
My read is that this is a cheap, contained experiment, and the line says as much: "not all of them become part of our operation." One Disney Treasure sailing, October 10 to 17, gives Disney data without committing the fleet, and the Virgin Voyages-style return bins outside the terminal suggest it is borrowing a proven playbook. Guests who already wear a DisneyBand+ are unaffected. The people who may lose out are souvenir collectors who will miss the card, and guests like the one who called wristbands a "sensory nightmare." The unanswered questions are the real story: Disney has not said whether anyone can opt out, and the room-power slot still needs a card. The irony is that the same week a guest joked about needing a platinum lanyard, the lanyard's contents may be going away. If I were booked, I would contact Disney before October 10 and ask about a card, and I would not read this as a fleet-wide plan.
