I have just spotted the lifetime Elite membership levels. One can see how many nights stay have been made since joining Marriott Rewards, but I cannot find anything in the account to show how many points have been earned in the period of membership. Points used simply disappear. Can anyone advise?
You'll need to call Marriott Rewards customer service for that info. I think there are plans to someday add that info to the My Account section -- just hasn't made it to the top of the to-do list yet for website managers.
