Yes, in 2026, you can use your Marriott Bonvoy points for your wife through a process called a Gifted Award Reservation. According to current rules, you must contact Marriott Bonvoy Member Support directly to book the stay in her name; this cannot be done solely through the standard online booking portal. You are limited to five Gifted Award Reservations per calendar year. Alternatively, you can transfer points from your account to hers, provided both accounts have been open for at least 30 days (if they have qualifying activity) or 90 days (if they do not). Marriott allows members to transfer up to 100,000 points per year and receive up to 500,000 points. It is important to note that if you book a stay for her using your points, she will generally not receive your Elite status benefits (like room upgrades or free breakfast) unless she holds that status herself, and neither of you will earn Elite Night Credits for the gifted stay.
