If it's a Disney Visa card, and not just a regular Visa, with a Disney picture, then you can use it in the park to purchase a few items that are for sale, only to Disney card holders. I saw a few pins that were only for Disney card holders.I don't believe there are any "perks," other than that. I'd contact the card company. They might have more answers for you. I was just at Disneyland. I recommend avoiding holidays, and being prepared to stand in long lines.
I am not sure about that, i am pretty sure you don't though.
