I would definitely recommend Garden Grocer to anyone staying in a Disney resort.
I read about Garden Grocer in a blog, and used your service on our recent trip to Disney World. I ordered breakfast foods, and they were delivered to our resort on the day we arrived, before we even got there! They were held at luggage services, in a refrigerator, until we got there. The service was excellent, and I appreciated the confirmation calls I got, both to confirm the order when I placed it, and to inform us that our order was delivered and ready. While it was pricey, we definitely saved money compared to buying breakfast at Disney every day.
Garden Grocer works great for us at WDW. We get breakfast foods and eat in the room. Then the Disney Dining Plan works for the Rest of the day. Delivers to the resort!
