Last year my husband decided that it would be cheaper to rent a car, shop for food and, cook during our DVC stay. While the car did allow us to hit Sea World for a day, it also meant hitting the supermarket more than once, and wasting my precious vacation time doing things I rather not do while on vacation, mainly, shop, cook and clean the dishes.
We ate out a few times TS meals as planned and, we enjoyed a good breakfast. That said, when we came home I did the math, and not that fuzzy disney math we all use to our advantage but, the real deal with all the receipts. As it turned out, if you add in the cost of a rental car, numerous trips to the supermarket and, a few meals out, we spent more than we would have had we just gotten the DDP.
So, this year we bought the DDP, for five of us for seven nights and, I wil be placing an order with We Go Shop.
No, wasting time - picking up/dropping off the car, shopping, cooking, cleaning dishes, pots & pans.
I'm ordering the basics, milk, cereal, fruit, frozen waffles, snacks, water, laundry cleaning things, wine, cheese, crackers
, and that's about it.
We will have breakfast in most mornings saving the DDP for lunch (CS), dinner (TS) and treats like ice cream (snack). I made my ADRs 180 days out, which I don't mind as we like to plan our days and my boys love to eat out on vacation (and they get to have dessert every night) as we really don't eat out much at home.
So, IMHO, the DDP works even when staying at DVC.
