Are you referring to the ART shuttle? If so, that should take you directly from your hotel to the Harbor shuttle drop off (look on Google Maps to get a visual of the route from your hotel, north on Harbor, then to the shuttle drop off area next to the Harbor bag check). If you want to take the free Disney shuttles from the Toy Story parking lot, you would have to walk from your hotel to the TS lot to catch those shuttles. (Again, look on Google Maps to see what that route looks like.)
