OK, I did a search on "password" before posting this. Another amazing enhancement brought to us by the idiots at Marriott.

My password was changed from a mix of lower and upper case to all upper case (and numbers). I have been using this password for a few months, logging in numerous times each week, so it's not like I forgot it. Today I was unable to log in. Had them email me my password and it was identical to my password, but all in upper case.

Just a heads up for rest of you.
