We used Garden Grocer for our trip to Disney. They dropped groceries at our hotel. I highly recommend this - especially if traveling with children.
This made condo life very easy. You can choose your items in the comfort of your home before your trip begins. It can be to the condo office before you check-in. Refrigerator items are kept cold for you. The prices were convenient store prices and paying a delivery fee is surely expected but not outragous. Would use the service every time. I will look for similar services in other cities as I travel.
