I got the Deluxe Dining plan the only time I used the Dining plan - and it was right after they made the switch. I went with the DxDDP, not because I wanted the appetizers, but because our trip was in January - and I wanted to make sure that as much was paid for in advance as possible.
I ended up spending a lot more than I thought I would for my one dinner drink and tips - and an expense I wasn't expecting, never having eaten at other resorts before...taxis! It's one thing to say "we'll take the bus to the MK and the boat to the WL" 3 months in advance...it's quite another when you're running late, and your ADR's in 30 minutes. Or when you come out of Boma at 8:30 at night, after a long day at the parks, sleepy & full - suddenly taking that taxi waiting right there in front looks a lot better than waiting on a bus to take you to DTD (or somewhere else) and then another bus back to your resort.
But I'm ready for December. I hope.
