Bottom line: Marriott doesn’t publish a list of hotels participating in this promotion, but if you enter a location, dates and promotion code in the hotel search fields, you can view all of the hotels offering a free third night in the location you entered. Be sure to search for stays of three consecutive nights or longer that include a Friday or Saturday night.
