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!
Was really nice for our holiday to get a few essentials ready at the resort when we arrived. Saved us heading out on the first night and meant we had time to just sit back and relax.
We've used Garden Grocer several times now. We order mostly breakfast items for our vacations but we used to order things like diapers and baby stuff so we didn't have to pack it! GG has always delivered on time - even early - and we have always been very happy to have our food waiting for us when we arrived!
