We're terrible about discovering and utilizing the perks and rewards and discounts available through our Disney Visa, but even so, we are taking advantage of a few this year, including a couple of meet-n-greets exclusive to card holders. I bring this up because they've just moved the Epcot meet and greet location from Innoventions West to the Imagination Pavilion, and the new spot looks awesome!
The card also racks up Disney Dollars, redeemable for purchases throughout the parks and Disney Stores worldwide. I have no idea how many we've accumulated. I figure I'll check when I start planning our next adults only, non-park trip.
We've used the card's early shot at the Free Dining discount before, and many if not ll discounts are offered for a few days to cardholders prior to the general public. That's really helpful in getting the room you like in the resort you most prefer.
Here's a link to the Disney Visa site explaining all the perks and discounts. Give it a look, you might just find a way to save yourself some money!
