Ok, my husband and I number crunched

just to see exactly what we would be paying and if DxDDP is worth it:
first, found out how much we were paying for DxDDP for 7 nights - 4 adults, 1 kid.
Cost on DxDDP: $2100.00 105 meal credits and 70 snack credits total.
Still would need to pay OOP for 2 meals for everyone, which would be breakfast as that is cheapest. ( since we are doing 1 dinner show and Cinderella Castle lunch while we are there and they require 2 meal tickets per person instead of one meal ticket per person.) But 70 snack credits are fine.
then, checked out updated menus and ordered all our meals and 2 snacks a day per person that we would NORMALLY order at the same restaurants.
Cost OOP: $2124.00 (these are the same places and food choices as if we were also on DxDDP, including 1 dinner show and Cinderella Castle lunch)
info:
-If we do DxDDP, we will need to still pay OOP for 2 meals for each person, which will most likely be some quick breakfasts as they would be cheapest for us to pay for OOP.
-did not include any tips already included or not
-we wouldn't normally order appy's or desserts at the restaurant so did not include that in OOP figuring.
-OOP plan includes 1 time 2 alchohol and 3 crazy kid drinks
-both ways include:
Spirit of Aloha Dinner Show
Princess Storybook Lunch at Epcot
Goofy's Dinner at Liberty Tree
Cinderella Lunch
Breakfast with Lilo and Stitch
Sci Fi Lunch
50's Prime Time
the rest of our meals are quick service
Cost of DxDDP per adult per night is $69.99 x 7 nights x 4 adults=$1960.00
Cost of DxDDP per child (3-9) per night is $19.99 x 7 nights x 1 child=$140.00
Total Cost of DxDDP=$2100.00
I'm sure that there could be other charges both ways that we didn't include or think about when we were doing our figuring but we are going to stay on the DxDDP for the main reason that the cost is so close that convenience of meals paid for in advance is great and we might as well go ahead and try the yummy desserts - what the heck - they're already paid for!

I hope this helps anyone out! P.S. Thanks Tricia for your help!
