If you plan to do any TS meals, especially buffets or character meals. I'd go for it.
In June there is a $2-5 added to the price of the character meals, so you'll probably save $10 at each meal, just by being on the plan. You'll also save 6.5% more because the taxes are considered paid with your DP fees. Finally if your children are between the ages of 3-9 the cost for them is $9.99 per night. There isn't character meal that cost that little for them. So it's like getting the CS meal AND snack free for them that night.
You can use CS credits at the water park and I think there are snacks available there as well.
There are no words to describe the "comfort" of being pre paid in the Mouse's world, just makes it that much more magical.
