Magic Band replaces Key to the World card at Pop Century

WDW Magic reports that guests at Pop Century will now be getting the Magic Band instead of the previous key card. 

During the past few weeks this has been tested with cast members and a limited number of guests, but from later this week, all guests at Disney's Pop Century Resort will only be issued with MagicBands.

Key to the World Cards can be requested, however, the magnetic strip will not be activated, meaning it cannot be used for traditional FASTPASS, only FastPass+

Disney obviously intends to make the Magic Band  pretty much mandatory at WDW.  I guess if you spend a billion dollars on something you would want to have it used as much as possible.
