In our experience, it's easier to get our money's worth with the regular plan. The average you need to achieve at the quick service is lower. The way we calculate how much we need to average is this for adults:
- QS: $19 per meal, and $5 per snack.
- RDDP: $17 QS meal, $42 TS meal, $5 per snack
With that being said, we will be using the QS in a couple of weeks. With a bit of planning, we were able to come out ahead on our meals. You just need to plan the restaurants and search the menus before hand. Also, if you have kids 3-9, the family average may improve, as some of the kids meals go well beyond the average for their price range.
I do feel that it's not advantageous to use the QS credit at the resort. It's hard to reach the average there. Specially with the unlimited mug refill, meals at the resort are probably best if paid out-of-pocket. Best to use the QS credits at the parks.
