I highly recommend Garden Grocer to any family visiting Disney World. It was so nice to have groceries waiting for us when we checked into our room.
They made this so easy to get groceries. We had a kitchen in our room, but no car to go the store. The resort was too expensive. This service was so easy, just click, order and set your delivery time. You don't even need to be there, they deliver to the Bell desk, who will put the cold items in the refrigerator/freezer. The called to confirm our order, texted us once it was delivered(which ended up being prior to our delivery time) and then called later to ensure all was there. The cost was appropriate and one flat delivery fee. This was an awesome service and would use it again when we come back to Disney World.
Super easy to use the website and awesome service!
