To get the rewards, they have to be transfered to a special card -- like a gift card -- that you then use to purchase things with the rewards.
You can call the number on the back of the Disney Visa card to get help on getting a rewards card and transferring your rewards points, or you can go on the
Chase.com website and access your account.
It takes about a week to receive the card in the mail, usually.
Probably the easiest thing to do is to go to one of the places
on property where they can give you a card (right then and there) will transfer your active rewards to a rewards card that you can use. I called Disney about this last Fall and was given this info:
Downtown Disney - by the AMC theatre
Downtown Disney - behind Ghirardelli's
Magic Kingdom Guest Services outside the park
Magic Kingdom Guest Services inside City Hall
They can issue a card within a few minutes (with photo ID and the Disney Visa card). Then call 800-300-8575 and go through the prompts to get to the Rewards menu. Then press 0 to get a rewards rep who will transfer the points to the card within 2 minutes.
Good luck and enjoy those rewards!
