I think the grocery services are great if you are not getting a rental car, or if time is limited. We built the time for a grocery run into the plan and it worked out great. We had a car and when we got to OKW, DH took the kids to the pool and I went to the store alone. this was for a 5 day stay, plus 2 more days at WL. We ate 2 dinners and 2 lunches plus every breakfast at OKW. We took the extra snacks/drinks with us to WL.

I made homemade spaghetti sauce (1/2 lb. hamburger, 1/2 onion, tomato juice, tomato paste, and seasonings I brought from home) - served over ravioli. this made 2 meals, a dinner and a lunch.
another quick meal - taco night, the rest of the hamburger, and fixings. The extra flour tortillas and shredded cheese made a lunch of quesadillas, and DD9 had "peanut butter rollups - PB spread on a warmed up tortilla and rolled".
we had pancakes/eggs 4 of the 5 mornings in the villa. we also ate a lot of snacks in the room on afternoon breaks and in the evenings.
I brought dryer sheets, microwave popcorn, coffee/filters and a few of the crystal light flavor packets from home. I also packed salt/pepper packets but you could get these from the counter service places.
next time I will also buy a disposable cookie sheet pan for the break/bakes.
