I ran into a booking issue today when trying to use a Marriott free night certificate, and it definitely gave me a scare. At first I thought Marriott had shut down my account and I could no longer use points. If this happens to you later, don’t panic—just wait a bit for the system bug to be fixed and it should be fine.

  • When booking in the APP, the free night certificate could be selected, but after clicking book, it showed: “We are unable to process your reservation. Please try again <invalid certificate number>”
  • Then I tried booking on the website, and it directly showed that there were not enough points to complete the reservation...

After asking around, it seems Marriott’s system may have glitched overnight. Don’t worry too much if you run into this. I waited about 3 hours, and then I was able to book normally again. I also checked with customer service, and they were able to see the reservation. If you’re in a hurry, you can try calling customer service to make the booking.
