Just got back from 10 nights of the
DDP (our first time, we have used the DxDDP twice), and I thought I would give you my experience with substituting at the QS restaurants I can remember.
Pepper Market: Most of the cashiers are aware of the changes, but even those who are aware get confused. I was able to substitute dessert, and drinks at when we wanted, for extra fries or other sides. They would not let us use soup as a substitute, but they said a side salad was fine. I did have an issue with substituting a bag of chips for fries on a child's cheesburger meal, but a manager walked out at just that moment and said of course we could do the switch. We were able to get three pastries for one quick service meal.
Casey's Corner: We were able to get extra fries instead of dessert, but it took the cashier asking another cast member, because she flat out said it wasn't possible.
Backlot Express: We were able to substitute dessert for fries no problem.
Quick Service at the Outpost in World Showcase: We got a hot dog and chips meal with two icees.
Starbucks (Epcot and MK locations): We were able to get three venti drinks for one QS meal.
Goofy's Candy Store: Three snacks for one QS meal.
Main Street Confectionery: Three snacks for one QS meal.
German QS: Three sides (potato salad, pretzel and nodel gratin) instead of meal. YUMM I am craving the Nodel Gratin right now! It took a manager to show the cashier how to ring it up, but they knew it could be done.
Even with the substituting this will probably be the last time we do the dining plan, we found out we really are eating less during our stays and we would rather have a quick breakfast in the room, which pains me as I am a dining plan lover. On the day before we left we had 16 QS credits, 11 snacks and 4 TS credits left! I used a lot of our QS credits to get Goofy's Candy Bags and Chip & Dale snack mixes to bring home, which I wouldn't have paid for if I had a choice.
