Well, for our last 5 or 6 trips to WDW we used the DP (always paid in order to get the room discount)and loved it simply for the convenience. Plus, our kids still loved character meals, so it seemed, whether or not it was true, like we were actually saving a little coin. But, on our last trip, again using the DP, we realized, as many have expressed here, that we were a) eating too much, and b) planning our day around eating. Also, our kids were no longer interested in characters. So, while we booked some of the places that DW & I had long wanted to try, it didn't feel as if the value of the DP was the same.
Granted it's a different system in Anaheim, but on our most recent trip to DL we paid OOP and let me tell you it was like a breath of fresh air. While we still made reservations, we ate less per day (1 big meal w/ snacks as opposed to TS/QS/S) and spent much less than we had budgeted.
So, due to this experience, we decided that on our next trip to WDW we're going without DP. Will it work, we're not sure but we're going to try it and see.
Hope it helps!
