These work exactly like the key to the world cards. You would have thought they would have gone with the obvious name "Key to the Land" but alas, they chose "Key to the Magic"

Disneyland fans have been waiting years for this, Now that WDW and Disneyland are run under one umbrella, hopefully they will benefit from each other's good ideas. For instance, I wish WDW would adopt Disneyland's AP system. You get a hard plastic card with a bar code, and your photo. When it's scanned you photo comes up on a large screen so the cast member can verify your identity. No finger scans! This makes the line move much faster. I can't stand the lines waiting to get in to WDW parks.
