Garden Grocers is a must for our Disney trips. We have a couple of cases of water, beer , snacks, cereal and fruit delivered. I order in advance and it is always available when we are checking into our room. Everything is fresh and the prices are that of a supermarket. We save a ton of money by ordering these things and it's so simple.
Perfect for a Disney stay! They deliver to Bell Services, who stores it (incl. refrigerated/frozen), and brings it to your room at your convenience. The groceries are high quality and on-time. The text messaging service to let you know the order has arrived is really helpful!
