Instead of receiving a Keys to the Kingdom card, which was previously used to open the door to your room, all resort guests are now issued a MagicBand. If you book your resort stay far enough in advance, you will be able to pick a color and have the MagicBands sent to your home prior to your vacation. If you don’t, no worries—you’ll receive a gray one upon check-in at your resort.
