Yes!
Be sure to pick up a portable perks booklet. If they don't have it at the check-in desk, go to any
DVC kiosk and get one.
Unless it has changed since we were there last summer, you will get a discount at virtually every table service AND counter service restaurant in both parks, all 3 hotels, and DTD. Take the booklet with you in case you need to show it to the waiter. When we were there, the discounts were very new, and not every restaurant was even aware of it. But we had no problems once we showed them the booklet. Hopefully that has changed by now.
