2.. Your MagicBand serves as a key.
The MagicBand that you customized online and received in the mail after booking your Walt Disney World Resort Hotel room will not only serve as your ticket to access each of the four theme parks and two water parks (with valid admission), but it will also serve as the key to your hotel room. Simply tap the sensor next to your hotel room door, and you will gain access to your room. (Photo credit: Disney)
