We used the quick service dining plan and we absolutely

it! We are a family of 4, two adults and two children under 9. We were there for 6 nights, arriving very late the first night so we only used 1 credit each that evening.
It was a great choice for our family because we enjoy eating at some of the more expensive counter service places, ie. Wolfgang Puck express, Tangeriene Cafe. We are not hot dog and hamburger type of eaters. If this is your type of food, then the quick service plan may not be for you. We got the least bang for the buck when we ate at Earl of Sandwich (which I do love by the way) because their meals are very reasonable anyway and they don't really offer any type of combo meal on the menu.
This plan also includes dessert with each meal and to be honest, we just don't eat that much dessert. We ended up getting things that were well packaged and could travel well and now they are in my fridge/pantry. I have a couple of brownies and a couple of chocolate cakes left. When I factored how much the dessert cost and took that off the total price of the meal, we still came out ahead of what we actually spent.
This plan also includes the resort refillable mug and it was the exact same mug design as last year. I don't know if they are trying to sell through the old before unveiling a new design. We really did not use the mug very often, only in the mornings for our coffee, which we made in the room. The drink station at Goods to go at Old Key West was just not convenient for us to swing by very often and they didn't have the hot chocolate machine like at Saratoga Springs, so we didn't have much use for that. However, the mugs we had at home were looking shabby so we were able to replace them. Yippee!
You get 2 snack credits for each person each day and we ended up with 22 unused credits on the last day. I went to the confectionary at MK and used some on cookies and fudge and the rest were used at the general store at Old Key West on cokes, candy bars, and chips for the drive home.
Each meal I wrote the meal total on the bottom of the receipt and I added them up each evening. We averaged $115 each day (including snacks) and the quick service plan was $78 a day, so we saved approx. $200 this trip on food.
We will definitely be using this plan again.
