FYI - change your passwords if you haven't in a while....Woke up to an email at 6am saying my password was changed....which i didn't do; completely locked out of my account. the mega frustrating part is that Marriott Rewards Customer Service is not available until 8:15AM EST (...??); regular customer service could not help. Once I finally spoke to someone they told me someone transferred 17,500 miles out of my account (which they will reverse, but it takes 3-5 business days)...so just a word of caution, its a complete pain in the a**, but change your password to a difficult one...
