We are staying at the Old Key West Resort later this month - having obtained a week through exchange via Interval International. We may decide not to rent a car. In that scenario, can one have ready access to the supermarkets. To put it another way, are there community supermarkets (eg Goodings, Albertson, Publix etc) in Disney World (Lake Buena Vista) that are accessible via Disney World transportation? Does Disney World have its own supermarkets - which in this case I would presume the groceries in these stores to be much more expensive that the community supermarkets?
