What feature allows Disney resort guests to link their park tickets to their room key?

The feature that allows Disney resort guests to link their park tickets to their room key is the MagicBand. This innovative wearable technology streamlines the guest experience by serving as a key to the guest's resort room and also acting as a park ticket. With the MagicBand, guests can enter the parks, access FastPass+ selections, and make purchases throughout the resort—all from a single device worn on their wrist.

This integration enhances the convenience of the Disney experience by reducing the need to carry multiple items, such as a room key and individual park tickets. The ability to link all these functionalities into one band also contributes to a seamless experience during visits, making it easier for guests to enjoy their time at Disney without interruption.

In contrast, while the Key to the World also functions as a room key and can be linked to park tickets, it does not provide the additional features and convenience that MagicBand offers. The other choices, Park Pass and FastPass+, refer to different elements of the Disney experience and do not encompass the integration of room and park access that the MagicBand delivers.
