So if you will have a car as stated above there are many Publix locations around the Walt Disney World area. There is also a Walmart close by that is huge. It can be very busy at times, but the prices are good and lots to chose from. With no car the Gooding's at The Crossroads delivers to the resorts as well. Also in the area I've seen people use Amazon Prime Now service to bring items to the resorts and Turner Drugs has small items like water and snacks. If you have a Military ID the Shades of Green Resort has an exchange on base which carries cases of water, bread, milk, chips ect.
