Your post is a little confusing; I'm not quite sure what you are asking. Chase has a Disney-branded Visa card, in 2 formats. Regular earns 1% in rewards points and Premier earns 2% at restaurants, gas stations, and grocery stores and 1% everywhere else. These points build up in your account until you request they be transferred to a rewards card, which Chase will send in the mail. The rewards card holds the cash value of your points. You can use this value for a variety of Disney-related purchases. SOME of the restaurants at WDW (not sure about DL) give you a 10% discount if you pay with your Disney Visa card, but you have to ask about it. Participating restaurants are listed on the Chase/Disney VISA website.
We are going to WDW at the end of the summer. I have just requested that Chase transfer $800 (let's say) in rewards to my rewards card. The card has a 16 digit number on it and can be used at WDW just like you'd use a gift card, deducting $$$ from the balance with every purchase. I am going to use some of that money to pay off the balance on my trip package (I just give Disney the 16 digit number and they treat it like a gift or credit card) and will use the balance when we are in WDW, for food and souvenirs. I try not to use the rewards card at restaurants that give me a 10% discount (like Boma, Jiko, Biergarten, etc); instead I use my premier card, get the 10% discount, and earn 2% in cash back towards my next trip. I figure that I'm going to "pay" out the entire balance on the card anyhow, so I might as well charge meals where I can get a discount and earn the 2% back.
