Most people if they stay at the deluxe got a better deal by using the DDE card and getting the room discount with AP. Another consideration is how many are in your party for your room.
If you stay value, it's usually better to forego the room discount and do the the dining plan with 1-day passes to qualify for the package deal. The 1-day passes can be upgraded in the future for new APs, etc. Also, if you are at the tail end of you AP time, you can use those extra passes for another trip, as long as, you get the no expiration passes. In that case, you may want to get more than 1-day passes.
The dining plan has to be utilzed in the right way to be worth it. If you go to cheaper restaurants or you skip meals it may not be worth it.
You have to do the math and plan your trip ahead of time and crunch the numbers.
