The wonderful new system that was introduced this week seems to have led to complete collapse. I tried to log in yesterday with my correct details, three times, and was locked out. When I phoned, I was told that they were having problems, and that I should try again in 10 minutes, or re-register. I tried again this morning, and was still locked out. I tried to re-register, but the system said that my details didn't match their database. Does anyone know what's going on? Note: it would be nice if Marriott Rewards were to send an email to members with some information.
