We have also been happy with Garden Grocer. A little pricey, but very convenient . You can pick your time, and have it delivered before you arrive or while you are at the parks, and resort will hold it and then deliver, like they do with luggage from ME. They have a good variety of items, like apple slices, gogurts, cereal, pop tarts, chips, goldfish, water, etc. Minimum order of $40 and $12 delivery charge.
