It does seem like from what I'm reading it has changed since last year. In Oct. we were able to get any 3 snack items using a QS at Pop food court. I asked a cashier on our first visit to the food court what snacks we could get with a QS credit. She said we could get "any" 3 snacks for 1 QS. We mostly did this for breakfast getting 3 pastry items. We did get 3 sundaes one afternoon for one QS. I did ask a manager type prior to ordering them. The cashier had trouble entering it and he had to tell her to press the Continental Combo button first and it would work-it did!
Now from what I'm reading you can't do this any more.
Personally, I think it makes sense for Disney to allow you to use a QS for 3 snacks. 3 snack items ( like our 3 morning pastries) are going to cost less than a lunch or dinner meal. This year I think we will have to limit ourselves to breakfast in the room from our own cereal, bagels, toast, etc. It's just never a good value to use QS for breakfast.
This will probably be more of an issue for us this year since we now only get 1 SC per person and 2 QS on the QSDP. I see us having more QS to use up at the end of our trip than SC (esp. since we are going during F&WF). I can see us ordering a QS meal and then discarding the entree just to get the drink and snack. Oh well.
Oh, last year while at EPCOT while DD was doing the KP thing, we felt it was time for a snack. We got a tartine, napoleon, and large diet coke from the Boulangerie for a QS but it was more like 3 snacks. DD ate the tartine, my DM and I shared the napoleon, and we all shared the DC. We will definitely have to do this again this year.
(I'm hoping that since we are going during free
DDP in late Sept they will have changed this policy or relaxed it a little.)
