We are going in January... 5 of us total but only having to pay for 4 adults as DGS is going to be 2.. So if the other 2 kids are under 3 then you will only need the dinning plan for 5. Other wise you will need 6, but the price is a bit less for children up to 9..
2017 Disney dinning plan
QS meal plan - - 2 quick service meals ( meal and drink included), 2 snacks and 1 refillable mug ( only good at your resort Food Court), ... 46.34 for adults, 20.18 for kids 3 to 9 --= per person per day
Regular dinning plan - 1 table service meal ( meal. drink and dessert included), 1 QS meal (meal and drink included), 2 snacks, and 1 refillable mug - 67.33 for adults, 24.22 for kids 3 to 9 -- =per person per day.

The regular dinning plan works great for If you are wanting to do some character meals, and Mom and Dad need to be waited on to...as its their vacation too.
With 2 snack credits, they don't have to be sweets, you can use them for savory items as well, You have to do your homework so to speak on the snack options, you could make a meal, or add to a meal your having that you might be splitting. Buy water don't waste a snack credit on water...
The mugs come in handy, DH would go get coffee in the am while I was helping kiddos get dressed, When we used a stroller we would wash them out store them in the day bag, and hit the food court on the way back for some beverages, and maybe a snack or treat to end the day. They are great pool side, so you are not spending a lot of money on drinks pool side not unless they are adult beverages that mom and dad deserve for bring the kids to see Mickey and the Gang... and they are a great souvenir..
You have to get creative when dinning at Disney... No matter what you choose to do have a magical time...
