NOPE.
Bonnet Creek sidewalks don't even make it out to Buena Vista Drive. There are no sidewalks on the Disney Springs side of Buena Vista Drive except for small sections to get folks to the pedestrian bridges. And to the west no sidewalks until you get to the Speedway/Boardwalk/DHS area.
Disney does not offer much sidewalk at all because they do not want you walking, if you try you will likely be stopped by security. Just not a safe option.
If you stay in WBC Club you can reserve and pay for bus shuttles to all areas. If you stay at the Grand the bus is included in your resort fee. They are not the same bus service. Or you can drive where you want to go OR use ride share.
