I don’t think they put together much of a hex crawl. With hex crawls you find places on the map in almost every hex. You may even return to them for various reasons. Maybe there are some empty hexes, but generally just between actual locations.
I think WOTC would have done well to present rough idea of TWO locations out in the grid – and nearby, like two or three hexes away from port Nyanzaru. Each location, when found, would then present information as to another two locations (sure, eventually you’ll run out of locations so some of the latter ones can reveal other locations already known about). This presents the players a choice, which when engaged presents them another choice, etc. Soon enough you have a map filled out with locations, or areas to explore in to find locations and possibly interactions between locations – ie reasons for PCs to actually go back to a place.
That or fill a whole bunch more of the hexes with actual locations. That’d be preferable, but for page count reasons the dual linked locations probably works more.
