Business and leisure travelers alike like accumulating points, whether they come in the form of frequent flyer miles, hotel points, tier credits, or points earned at casinos. Given that Marriott and MGM are the organizations behind the two biggest loyalty programs in the hotel and casino industries, it makes reasonable that they are utilizing this concept. While Marriott Bonvoy has more than 180 million participants, MGM Rewards has more than 40 million members. According to the conditions of the license, MGM Rewards members can "link accounts with Marriott Bonvoy and receive select member benefits" while members of Marriott Bonvoy can accrue and use points at all MGM facilities that are a part of the deal.
