you acrue disney dollars, that can be spent at the world.
I think you get an interest free grace period if you book and pay for your disney vaca with the card, or that may not be a perk anymore, you'd have to call and confirm.
they have several neat looking options for the card - the red card, mickey mouse, and a few others, by request - I just saw this in one of there newsletter junkmails.
any others?
