I was trying to decide whether to get the dining package for
DVC members for our upcoming visit. I sat down with the receipts from last year's trip to get a reasonable idea of how much we spent on food. We bought groceries for breakfast, juice, soda, and water and prepared breakfast in our room each morning. We always ate lunch and dinner in either the parks or Downtown Disney. For our family of four, we spent $536 on 9 dinners, $292 on 8 lunches, $91 on groceries, (10 breakfasts, drinks, snacks). It worked out to about $26.25/person/day.
This includes dinners at Wolfgang Puck Express, Liberty Tree Tavern, Trails End, Irish Pub at DD, Rose & Crown, Tony's Town Cafe, Tangierene Cafe, and the Earl of Sandwich. We had lunches at the Whispering Canyon Cafe, Pecos Bill's, El Pirata, Flame Tree BBQ, Pizza Planet, Columbia House, ESPN Zone, the Tangierene Cafe, and the Earl of Sandwich.
We had plenty to fill us up, only made three priority seatings, ate when we wanted, where we wanted, so I'm thinking that the extra $48/day that the dining plan costs isn't cost-effective for us and we probably won't spring for it next fall.
We did have the Disney Dining Experience card, but how much it saved us versus how much it cost is uncertain. It will still be valid on our upcoming trip, so I guess the benefits will cover two trips.
