Have to disagree with PP's calculations.
We are just back from a 7day/6 night trip last week (Jan 30-Feb 5) and DH loves to keep our receipts (we were on the DDP).
Each day our lunch at a CS ranged from $30-$42 per day for the 2 of us.
(the $42 price tag was lunch at WPE at DTD)
For dinner we averaged around $78-$85 per day for the both of us.
Our dining plan was free but if we would have paid for it, it would've been around $90 per day for both of us.
As you can see we would've saved money with the DDP. As lunch and dinner every day would've averaged $108 - $127 OOP.
Now that doesn't include the snacks we got, which avereged $4 each, so that is another savings.
Of course if you don't eat dessert or have a drink with your meal it is cheaper, but when on vacation we like to do so, so we save money with the plan. (it is even so much better when it is free dining)
Go ahead and take a look at the menus, most prices aren't totally correct, but they give you a good idea. Just think it will be a bit more and you will be ok.
FYI....2 hot dogs and 2 med sodas at Casey's in MK was over $15!!! That was no fries, no desserts. Repeat...2 hot dogs and 2 drinks.......CRAZY!!!
