I think the only Disney resort that you could possibly walk to an off-site restaurant would be Saratoga Springs which is maybe a 20-30 minute walk to some of the restaurants on 535 (Apopka Vineland rd), just outside the Disney entrance.Disney World is a huge place and most of the resorts are located several miles from off-site areas.A tourist area that is more conducive to walking to restaurants from your hotel would be an area like International Drive.
