I had a few Visa giftcards last year that I received as a rebate that I tried to use at AOA to bring down my room balance. I saved them just for spending money at Disney. It was a pain! The card would only deduct a few dollars each time the CM ran it. She ran it over and over and each time it would just take 2 or 3 dollars off the card. Turns out you really need to run this one for the exact amount on the card. This year I got another one (same rebate). It was worth $50 so I took it straight to Target and bought a $50 Disney giftcard. Problem solved! If you know how much you will use at Disney, I'd go with Disney gift cards for most of it and then you can maybe keep a few of the cards for other things. You might want to be able to have the CM run the visa cards for a specific amount.
