DDE should I get it?

[SolitaryPhoenix]

Excellent, excellent decision to get DDE. I used it for my party of 7 last month, and it more than paid for itself. We had breakfast in the rooms, AR's for one sit-down restaurant for lunch, then usually ate at food court for dinner - and the food court at Pop Century also took the discount. Usually, my teenaged niece and nephews went back to the parks at night after dinner leaving us 'old' folks (and my youngest nephew) to relax and recharge. Worked out great.

It is a great option if you are planning to eat at a lot of Disney sit downs restaurants as well as counter service at Animal Kingdom (it's good there since AK has no sitdowns). I stay at Pop Century a lot and it's good at their food court (note that it's good at all resort food courts where there is no sitdown restaurant - values and POFQ). It's also a great deal if you're planning on indulging in some adult beverages, since the discount includes those.

Here's some very good info on the Disney Dining Experience card.
