Yes, you absolutely can. In 2026, Marriott Bonvoy has actually increased the annual purchase limit for members. A supportive peer "loyalty" update: you can now purchase up to 150,000 points per calendar year, up from the previous 100,000 limit. To buy 100,000 points, you simply log into your account on the Marriott website. At the standard rate of $12.50 per 1,000 points, 100,000 points would cost you $1,250. However, I’d suggest waiting for one of Marriott's frequent "Buy Points" promotions, which occur several times a year (including Q1 2026). During these sales, they often offer a 30% to 50% bonus, which would either give you more points for the same price or allow you to reach your 100,000-point goal for significantly less money. Just remember that purchased points are non-refundable and can take up to 72 hours to post to your account.
