We've tried to standardize the naming of area/city threads with "Marriott Bonvoy hotels in..." So as
dayone shows, just put the city name and the term "Bonvoy" in the search text field. If there is an area thread for that city it should show up. You can also search without the "bonvoy" in the search string, and you would then also get all the individual hotel threads for that city as well (as we have tried to standardize the individual hotel thread titles as well.)
