It is just $2.53 more per adult per night, $2.33 per child. On a 10 night stay that for a family of four that is $97.20; less than the cost of a Mickey Bar per person each day ($140). Not sure why this would alter anyone's decision on whether to do the plan, especially since menu prices will rise as well.
For me, the DDP was minimal value in the first place, not counting the Free Dining promotion for my trip in Sept/Oct, it would have saved me roughly $20 over the length of the trip, (9 nights), so this does tip the scale in the opposite direction (9 x 2.53 > 20). Of course, for my solo trips, I don't consider DDP anyway since I prefer to dine differently.
The DxDDP hit is huge though. at ~$14 per night per person increase, this will shift many of the balance points (break-even, QS/TS ratios, how many can you skip) quite a bit further off their mark than they are now. Math will take some time to work out for those, but we'll see what we come up with.
For the credit costs, going back to Faldred's original calculations, we see the following (assuming all entitlements are the same):
2QS + 1S = 37.58
1TS + 1QS + 1S = 55.59
3Dx + 2S = 99.97
Using 3 for S (to symbolize an average of $3 for snack) we get
2QS = 34.58
1TS + 1QS = 52.59
3Dx = 93.97
QS = 17.29
Dx = 31.33
1TS + 1(17.29) = 52.59
TS = 35.30
So, in non-peak season, these are the rough estimated costs per credit per plan:
QSDP: 1 QS credit costs ~$17.29
DDP: 1 TS credit costs ~$35.30
DxDDP: 1 Dx credit costs ~$31.33
(*Cost per credit, at least in my world, is an estimation of how much the actual credit costs you when you buy the plan. There is no bearing on what you order, or how many credits you leave unused, since you still have them, they're just not used. Value per credit is where these things come into play. Again, at least in my world

** ETA: I'm also going to go ahead and assume that the original numbers posted are correct. I'm sure they are, but when I was going to check via the formulas I used last year, I couldn't easily find a constant room to use to compare peak and non-peak across the different use cases I had created. As such, I gave up and didn't feel like doing it
