My goal wasn't to save money, rather do what we wanted and eat where we wanted. Rather not be bound by using credits because you paid for them and didn't want to waste them. Granted we didn't purchase meals for my son at every dinner nor did we eat two desserts at every lunch. The last several times we went on the DDP we left several CS behind and I still have bags of lollipops and jellybeans in my pantry.
You have to remember that two of the meals that we did enjoy were signatures and we would have been short dinners two nights on the DDP.
Also granted we didn't get two adult desserts per meal, but we always got an appetizer and a dessert. If you remember from my post the app at the California Grill was a $20 Sushi app that was awesome btw.
The only night we ate two desserts was the night at Kouzzina where we had a $10 app and then two $8.00 sundaes at Beaches & Cream (which I didn't count toward against my paid snacks). I put up the sundaes at B&C against any other dessert.
And our snack count was only 4 short for 8 nights which isn't bad. I know people leave that many snacks on the table all the time. And we weren't bound by what Disney calls a snack. We had several items that were not approved DDP snacks.
So yes, we spent slightly more but I feel that we ate so much better. Plus my meals were portable (LegoLand & SeaWorld). And God forbid one night someone isn't feeling well and wants to skip a dinner, you are not out a credit. You can also share a meal. Eating 8 nights like that you tend to get stuffed.
Even if we weren't going back this summer and didn't get to use the TIW again, I would still do it again. Overall the extra $133 spent was well worth it. I don't know what I would do for a single shorter trip.
We did not deprive ourselves in any manner.
Using the DDP is an exercise in constantly trying to beat the system by eating the most expensive meal all the time and using all of your entitlements. On OOP I can still eat dinner at Le Cellier without using a signature
